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.

When you get pissed off at someone for being a hypocritical fetish/kink shamer but you still want to wank one out
Hypocrite: ANYONE WHO LIKES NTR SHOULD DIE!
You: Well you must be pretty fucked up for liking lolicon, incest, snuff, guro and cannibalism huh?
Hypocrite:........
*You then proceed to your angry masturbation*

When your mechanical pencil is out of led, so you repeatedly and forcefully push the eraser to make sure that you don't have any extra led in there. The sound it makes is like fapping. When led comes out, it is called pencil ejaculation.
