I tend to think left 4 dead's Boomer zombie.
Slightly unrelated but when people say Zoomer, I often think about the hover bike from the first Jak and Daxter. XD
Definitely l4d boomers. I still play it once a year with the buddies. Install, play 1-2 hrs, goodnight, uninstall, repeat next year.
As a millennial:

Also, Boomer from BSG, but I was mostly just jealous of her because of Galen.
BOOOOOOOOOOOOOOOOMMMMMMMM...
Still haunts my nightmares
I can't see it without hearing the noise
Boom!
Grind!
I loved this game so much.
Gotta admit, I get the hate against boomers. Like, they literally shoot you with artillery when you first try to approach them. (Pro tip: stay close the the rocks, might save your life)
GRIND
I always think of the Boomers in FONV.
