spontaneous masturbation

Jacking off at random times in random places. If someone is a spontaneous masturbater, you never know when they will just whip their dick out and start beating it.

Zach pulled his dick out in the middle of the cafeteria and started pumping it. This is an example of spontaneous masturbation.

Time Sponge

A place on the internet where you go just to check something out, then spend hours playing - like typing names into Urban Dictionary

I spent an hour elf bowling - it is a definite time sponge.
