trisexta

When someone achieves having sex with three different partners in the same week they have hit a trisexta. Root/origin of term from sportsbook Trifecta e.g where a bettor gambles on 3 different horses in the same race to win, place and show.

I banged Alan on Friday and Steve on Saturday. My new hot dude, Caleb, is coming over on Thursday and, if he's into banging me, I think I'm gonna finally hit a trisexta.
