O-ring Domination 

After you give someone a pink sock, you cut the sock off and wear it on your wrist.

Guy 1, "Dude, check out your wrist! You killed her o-ring! No, you dominated her o-ring! That's some crazy ass O-ring Domination!"

Guy 2, "Yeah, I don't play around."

Guy 1 "Why are you walking like that? Did you just Blow an O-Ring? "
Guy 2 "Ate some nasty food the other night...God it hurts!"
