The act of performing cunalingus on a special female while she is on the toilet taking a dump. The smell may be horrific but when its your turn to take a dump and get a blumpkin, the result will be EPIC!! P.S you are a sick bastard...
Steven decided to give his girlfriend a moon pie because she promised to give him a blumkin. Steven doesn't discuss this experience!

moon pie is an actual product! it is a chocolate, marshmallow and grahan cracker (smore like!) confection/junk food snack pie, round in shape. exclusively seen/eaten in the south. they are commonly sold at gas stations and truck stops and as such has a rep as a white-trash product. i have seen one, but never eaten one. paired with a drink to "wash it down" which i THINK is usually milk. some of you southern red necks need help me put here.
a moon pie is a real food object!
