Thumb Cum

The art of spilling one's sexual mustard onto his thumb after a session of masturbation.

I ran out of tissues after I had a wank lastnight, I couldn't wipe off my thumb cum!!

The Tasmanian thumbcumber

When a cucumber that encases an opposable thumb, is shoved repeatedly, slowly, and with passion into an orifice of the body.

Evan and his dad love preforming the Tasmanian thumbcumber together, but coach krumplesack prefers to go at it alone.
