Boner Friction 

Noun: A competition played between two straight males in which each man develops an erection and proceed to rub their boners together. A winner is crowned when one man's boner stays hard and the other's goes flacid.

Note: Regional rules apply: Different areas define a victory by losing your boner first... in other areas the still-stiff man is the victor.

Regardless of differing regional rules, "No Homo" is in effect for the duration of the competition.

Tim and Dan played Boner Friction until Tim lost his erection and Dan won.

What the friction 

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.
