when a girl is on top of a guy and intentionally or unintentionally comes up too high and then down again really hard so that the guy's wang comes out while she's up and then gets painfully bent when she comes down because it doesnt have time to re-align for for re-entry.
"How was it the other night with that chick?"
"It was great until she gave me a jammed finger"
"ooooooouch, sucks man."
