Gumpin

A cliff at dolime quarry in Guelph Ontario. The name came to be when some drunken idiot (read: typical cliff jumper) tried to spray paint "Jump In" but managed to spell "Gjump In" which has now been shortened to "gumpin". A gumpin is also a measurement. 1 gumpin = ~25ft
a gumpin is not a static measurement because a gumpin is defined as "the distance from the top of the cliff to the water" thus a gumpin is never the same.

S: I dare you to dive off the gumpin!
T: I dare you to gainer the gumpin!
S: I dont know how to GAY-NOR
T: It's "gainer" not gaynor, you fucker.

Dude that cliff is like 3/4ths of a gumpin.

Gumpin is pronounced "Guu-om-pin"
-
the amount of water in dolime quarry is 36 gumpins cubed (i.e. 36g^3 opposed to 300m^3)

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.
