I've had quite a few names that I really liked. Some examples:
"Bitter Cold on the Frozen Tundra" - I brewed this IPA in my garage when it was snowing and about 2 degrees F outside. I had a chilling SNAFU so it took much longer to chill than expected, which led to excessive isomerization of late boil and FO hops and made it a bit more bitter than expected. My BIL and I froze our butts off brewing that. Really good beer though.
"Frau Meow" - I have a cat that meows with a gutteral ending that reminds me of some German words that sound like someone is clearing their throat (think how "Frau
Blücher" is pronounced in Young Frankenstein). I said she meowed with a german accent. When my daughter wanted me to name a beer after her, I called if Frau Meow.
"Brut Flutin' Boogie" - my brut IPA. It had a champagne type feel to it, so I joked about drinking it from a champagne flute. The name came from that, combined with a country song titled "Boot Scootin' Boogie".
I had a series of NEIPAs with the same grain bill, just different hops. All were named an animal in the name where the animal had some relation to where one or more of the hops were from:
Platypus Venom - Australian hops
Armadillo Juice - Amarillo hops
Honey Badger IPA - added gambrinous honey malt
