A frequently occurring event wherein, something is inserted into the vagina (a finger, a tongue, a GI Joe doll, etc.) and something else is lost on the way out (a ring, a condom, a fake mustache, Snake Eyes' kick ass Uzi, etc.).
Damn, Civilian, I was finger-banging Kalea last night and I pulled a sub-ham, minus-ham and lost my class ring. I hope Jostens refunds my money, yo, that shit had the Chandler High wolf on it!
