I don't know about 'iconic' but I once heard my grandpa say "I'd eat 5 feet of her shit just to see where it came from." and that mental scar will probably stay with me the rest of my life.
From my mom, not my grandparents, but we've gotten a lot of mileage out of this one
"If I find it, can I hit you with it?"
Used when we were bugging her about not being able to find something. Don't believe she ever made good on that threat, but it usually did it's intended purpose of getting us to quit bugging her and find it ourselves. And if it was something we really needed help finding it would have been an acceptable trade-off.
My sister got a lot of use out of it with her college roommates and my wife and I use it with each other pretty regularly.
My grandpa had a million one liners, most were somewhat inappropriate but here's a fun one. He'd say, "Did anyone get hurt in that wreck?" To any of my friends that drove over. When they inevitably asked "what wreck?" He'd say, "the one you pulled up in." This was devastating to the ones who were super proud of their cars. Lol
My grandmother said, "The time for tarts are when they're passing." She meant "take what's offered when its offered," but I want it printed on the programs at my funeral
It's not so much a catch phrase, but words that I will always remember.
My grandmother was a WWII vet who came home and vowed to be a pacifist. She raised 7 kids before going back to school. She was at Kent State in 1970, working on her masters degree. She happened to be on the commons when bullets started flying.
She died ~2002. When we were cleaning out her belongings we came across a brown stained handkerchief in a plastic bag along with some news clippings. The clippings were her letter to the editor of the Akron Beacon Journal describing her experience on May 4th. The hanky had a little handwritten note that said "this is the blood of Allison Krause. Shed for many. May 4th, 1970".
My grandmother was an amazing woman who did so many great things after the war. You could easily write a movie about her accomplishments. But out of everything she did, the words on that little note made the biggest impact on who I would grow to be.
“You may have descended from monkeys but not me” from my grandma. She was a stubborn woman who had a hard time adjusting to the idea of evolution. I’m mostly atheist but I still get a kick out of this one
All my grandparents passed when I was young and I didn't know them well. However, my uncle quotes his father quite a bit. General advice "Never do anything you wouldn't want to read about in the paper." Whenever he offers you something, or is jokingly telling you why you shouldn't do something "It will make your babies come out naked and screaming" Also my mom's side of the family has a common last name and my grandfather stated that if we met another person that shared our last name that we could accept them as family if they were "reasonably dressed, moderately sober, and not asking for money"
My Pop, whenever he was asked where something was: "It's in Annie's room, behind the clock." There was no Annie in our family, nor a bedroom with a clock you could put things behind.
Also my Pop whenever asked what something was: "It's a wig-wam for a goose's bridle."
These may not be iconic to anyone else, but they are sure as hell iconic in family lore, and us grand-kids are making sure we pass it down as much as we can.
My grandfather would say “Is your daddy a glassmaker?” And when we’d inevitably say no, “Then get from in front the tv!” Meaning we were in his way, as children tend to be lol. Me and husband use this all the time with each other.
My paternal grandfather had a lot of sayings: "here's me head, me arse is coming", "she walks with a bit of a run", etc - typing them out a lot had to do with the way people walked. There are more though.
Whenever I got hurt, my grandmother would say "It'll get better before you're married!" I use that to this day with my nieces and nephews, who are not amused.
My grandpa was german. In german, jetztwhich in english would be pronounced something like “yetst”, means “now”. His whole life he would use “yet” in place of where an english-native speaker would say “now”, and i always thought that was adorable.
My mother’s requests for us to calm down escalated over the years:
“Cool your jets”
“Don’t get your underwear in a wad”
“Don’t get caught in your zipper”
Mom says that my great grandmother had a notorious potty mouth. Whenever she'd get up off the chair she'd yell "oh, this heavy ass of mine!" ("Ay, este culo tan pesado!")
i've heard my appalachian dialect speaking grandmother use the word "quit" in the like 1700's british sense of "to leave." that, and she used to say that she was going to do something "directly" like "we're going to the store, directly." such archaic speech patterns.
the word "appalachia" is pronounced "app uh latch uh" btw
Whenever my Grandfather, a WWII combat veteran, saw something he didn't approve of: "The things you see when they don't let you carry a gun any more...".
My other Grandfather didn't really have any funny phrases, but my Nana when she didn't approve of something would just use the "Well, that's a how modern people do things I suppose". It was really the only complaint she'd make, the only time I ever saw her lose her temper with someone was the day I got into a traffic accident and she had to be physically restrained from going after the driver for hurting her grandchild hahaha (I was the passenger).
My grandfather was the cook most of the time, and he was always trying new recipies he found online: in years, I don't think I ever saw him cook the same meal twice.
Everytime he'd taste something new, he'd enthusiastically comment "it's different than usual!" (Rough translation from French "ça fait changment!")
To this day, I have no idea how good or how bad he thought any of those dishes were.
It probably doesn't translate very well. But my grandfather always said something like "If you don't behave I'll put your head between your two ears" and us kids would always giggle and say that it was already the case. I often use that phrase now.
"It's colder than Christmas". For reference I live in TX, so it doesn't take much for it to be colder than Christmas (it's not uncommon for Christmas to be in the 80s F).
Not a catch phrase, but one day my grandfather showed up at the house unannounced asking me to bury his pet cat that had recently died in my back yard.
