What you don’t realize, is that by Googling “onion booty”, you probably created that site! :-) The Quantum Internet Porn rule says, “if you can think if it, it’s there”. (The spammers, of course, would have used a program to create random word combinations. I doubt that counts as “thinking of it”.)

On the other hand, I’ve seen “yoga booty ballet” around for years — indeed, I’ve seen it sent by spammers! ;-)
