RandomAnal seems like a good premise. Could go with a BangBus type pick up "Hey you're sexy, want some Random Anal? Are you sure, it pays $500? Ok, get in."

Or go with guys picking chicks up on a beach or at a club. As soon as the chick is naked the guy starts playing with her asshole, when she asks what's going on, he responds, "I was thinking about some RandomAnal. One night stands are good for experimenting. Give it a try, and see if you like it." Or,"I don't have any rubbers, so I thought we could have some RandomAnal."

However you do it, make it a tag line and not just a domain with random rehashed anal scenes.
