Jumpkin

Much like a blumpkin where you get blowy while dropping off a SEAL team, its when you jack off and take a shit at the same time because you're stuck in some third world shithole or... your parents house.

dude 1: hey man, hows it going? you've been in here a minute.

dude 2: it was going good until you interrupted my jumpkin

Jumpkin

The act of making yourself cum while simultaneously dropping a deuce.

My girlfriend wouldnt give me a blumpkin because apparently she hates the smell of my deuce, so I went into the bathroom and gave myself a jumpkin.

Jacking off while fingering your butthole, with the result being intense sexual pleasure.

After Pat's underwear were frozen, he sat in his room and gave himself a jumpkin.
