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.
