I use buttfuck/buttfuckin’ an awful lot as an adjective but not really as a noun. Come to think of it, I don’t often – oh, no, wait, when my cats are being unreasonable we do call them little assholes, but swearing at them turns it into a term of endearment anyway.

Dipshit, wanker, buttnugget, cunt, probably my top go-tos lol. I kind of love how some people just hate the word cunt.
