When a gangbang occurs (1 female and 2 or more males engaging in sex) and the men participating all are wearing backwards trucker hats.
Jas: Dude did you hear about the gnarly San Diego Gangbang that happened last night after that sick surf sesh?
Ricky: Yeah brah I was there! Three of us all had matching backwards Action hats!

Get the holy shit its sans Undertalemug. 
A brash, yet gentlemanly way to settle an argument. Should one accept the challenge, both participants face their backs to eachother and walk three paces. On the third pace both men face eachother, drop trow, and vigorously masturbate to completion. The winner is the first man to blow his load. Bonus points for ejaculating onto the other competitor.
Hey, did you hear about how mad Jason was when his GF was grinding on Tyrone? Good thing they settled it like men with a San Francisco Duel! Jason never saw it coming!!!
