It means what the fuck. It originated when I was playing a game at my friend's house and he beat me mercilessly. I then proceeded to beat him with a stick, but then I held myself back and said "what the friction" because his mom was in the next room.
I fucked your sister up the ass and videotaped it.

What the friction, man? Why didn't you send it to me before.
