Shank 

The art of taking a shit whilst having a wank. Great way to save time. Also heightening the pleasure factor, as a big firm dump squeezes past the male g-spot.

I had a monster shit last night. Time was not on my side, so I decided to double up and had myself an awesome shank.

Or....

My flatmate left the bathroom door unlocked last night, I accidentally walked in on him Shanking!
