plumpkin

Plumpkin is a variation of the more well known term blumpkin. What differentiates a plumpkin from a blumpkin is that the woman performing the oral sex on the man who is taking a shit is morbidly obese, or plump as some would say.

That porker gave me some awesome plumpkin this morning.

blumpkin on the spot

This is a variation to the more common term blumpkin. The major difference is that this act of receiving a blowjob while taking a shit takes places inside a port-a-potty.

I got a blumpkin on the spot from that chick at the Tom Petty concert
