shabumpkin

When playing the game Padiddle you can do the same with the tail lights of cars and instead of yelling Pdiddle! you yell Shabumpkin!

A car passes with one tail light Caitlyn yells "Shabumpkin!" and Nick and Michael take their pants off.

Shumpkin 

As opposed to the classic blumpkin where you are receiving head while shitting, she is shitting while you receive a blowjob!

Schuyler: yo this girl just sucked my cock while she was shitting!
Oscar: YOU RECEIVED A SHUMPKIN!!!
Schuyler: YEA and I blew my load in her hair
