Gumpin It 

The act of placing a living freshly caught shrimp, (or crawdad depending on your region) inside of your rectum in the manner of the hamster Lemmiwinks in the South Park episode "The Death Camp of Tolerance". There are some who swear by the more extreme variation "Bubba-Gumpin It" - in which you place two belts around your lower thighs in a tourniquet-fashion to pay homage to Lt. Dan.

Sorry I'm late, I was Gumpin it for the last hour or so.
