When, during sex, a finger/fingernail hooks someone's anus during intercourse, causing snagging and discomfort. Like the fishing term when the fish is hooked in the tail rather than the mouth.
I tried to hold on to my girlfriend's ass during sex, and I accidentally foul hooked her!

To unintentionally get laid randomly. Going to a club or party without any intent to bang but just by chance you meet a willing sexual partner.
“ How did you meet your wife? “
“ I foul hooked her at a club a while back. She was at a bachelorette party, I was bar hopping, and we met randomly at the shitter”.
