Whip Crack

A shock site that depicts a repeating video (sort of like meatspin ) of two males having anal intercourse with each other. The one on the bottom is repeatedly humping the other from above, which causes the other male above him (which looks like a girl) to have his penis go up and down like a whip, hence the name "whip crack".

"i just saw whip crack. by GOD that girl has a COCK!"

for the crack 

To do something for heck of it.

To perform a pointless action just for the sake of one's own entertainment.

I threw acorns at my brother for the crack.
