look up any word, like bukkake:
The act of intentionally restricting oxygen while masturbating in order to achieve a more powerful orgasm than manual stimulation alone.

Choking yourself while jerking off/flicking the bean.
Male 1: Dude last night I was asphyxibating and I passed out.
Male 2: Me too man! Asphyxibation is the new sex!
