slaumming
The act of two men going to a morgue and choosing a two to three day old dead women.  One of the men then places his mouth directly over the girls vagina.  The other man then proceeds to get a running start before jumping and landing as hard as possible on the womans stomach.  The rest is history.
"Dude, I just went slaumming last night with Jimmy!"
"The other day we slaummed with a four dayer"
