The act of grabbing your testicles in public and shaking them around like Christmas bells.

Dave was fucking knob-jangling in Tesco again !

When you jizz into a sock and forget about it for so long that the jizz starts to make mushrooms grow.

"Fuck bro I found a cum sock from like 11 months ago behind my bed, there was so many cumshrooms sprouting off"
