Definitions
Fuckheaded is a blunt, vulgar adjective meaning profoundly stupid or completely lacking in good sense. It goes beyond ordinary foolishness — someone who is fuckheaded isn't just making a mistake, they're operating at a level of dim-wittedness that's almost impressive. The word appears in heated arguments, frustrated rants, and any conversation where 'idiotic' or 'moronic' just isn't emphatic enough. Casual and coarse, it's definitely not for polite company.
It was genuinely the most fuckheaded decision I'd ever seen — he quit his job to invest everything in a cryptocurrency called SquidCoin.
