One of my first beers I watched in horror as a fly landed on the wort during boil and get subducted in never to be seen again. Named that beer Insecticide. Turned out pretty good.
I'm really not creative at all about naming my beers. But then it's not hard to distinguish my beers as I don't brew as often as I used to. So I can refer to my beers as "the 2022 Czech Dark Lager", "the 2021 10° Vienna Lager", "that Saphir-hopped German Pilsner" and "last year's osmička" (osmička is a Czech term for a beer with 8°P original gravity).
