Spontaneous Combust-a-nut

When you see a girl so hot, that you cant control your man parts, and you jizz in your pants unexpectedly

That girl walked past me and as i watched her walk away it made me spontaneous combust-a-nut!

The Stripper was grinding on me and before i knew it, spontaneous combust-a-nut

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.

Spontaneous Jack Towel

The towel that is kept handy by your bed side that is laid on top of the bed to prevent semen, lube, female ejaculate, Santorum or period blood from getting on the sheets.

Man, good thing we had that Spontaneous Jack Towel handy. That was a messy round of love making. The mood was not killed becaues it was handy by our bed side and now I can go to sleep knowing that I am not going to roll over into mixture of my semen, your ejaculate, and lube.
