When a guy, when he ejaculates, also defecates and vomits at the same time.
Tripling yourself, as discussed in Misfits...

Nathan: Just before I started my community service, I had an incident with this girl.

Laura: What kind of incident?

Nathan: Right... I picked her up in this dentists waiting room (she was having some sort of oral surgery). So we go out, few drinks, couple of kebabs, then it's straight back to her place to start with the shagging.

And I've built up a nice rhythm, and I'm getting really close to blowing my load, just hovering in the pleasure zone... and then BAM! All hell breaks loose. I tripled myself.

Pause

Laura: Sorry, I'm not familiar with that term.

Nathan: You know, tripling. It's when you cum, puke and shit yourself all at the same time.

Kelly: For Fucks Sake...

Nathan: Three bodily functions: doing the triple.

(John) You managed to triple yourself? YUCK!

A slang term for when you cum, puke and shit yourself all at the same time.

To defecate, piss yourself, and cum all at the same time. Popularized in movie The Misfits and is used to describe the physical reaction to serious, often nerdy, excitement and fan-hype.
Dude, when the new Call of Duty game was announced, I tripled myself!

I can't wait for the new Gorillaz album! I'm tripling myself thinking about it!

Dude, don't triple yourself over the new Transformers movie.
