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*
