look up any word, like sex:
 
1.
the sexual acrobatic super move of completing a double blumpkin by 69ing and simultaneously shitting.

*Warning*: NOT for recommended for novices.
Billy: Hey, can you give me a blumpkin?

Jill: Only if you give me one too!

(Both begin to chant, beginning in a soft whisper, and slowly building in volume and frenzy): BLUMP TO BLUMP!, BLUMP TO BLUMP!, BLUMP TO BLUMP!
