sistine chapel

When you're getting a blowjob from a girl and you jizz on the roof of her mouth.

Sandy always wants me to give her a warning before I come, but fuck that. I gave her a steaming hot sistine chapel surprise. Scrape your teeth again, bitch.

Sistine Chapel

Just like the Eiffel Tower, where two guys hi-five while both being pleasured by one female, the Sistine Chapel includes one more female. Both couples are in doggy style, with the girls making out in the middle, and since the guys are too far apart to hi-five, they instead resort to a finger tip touch, much like God and Adam.

"Did you hear about the orgy last night? Corey and Tyler totally pulled off the Sistine Chapel with Kendall and Bella last ."

Sistine Chapel Shit

When a man takes such a massive shit that he must flush the toilet half way through and then continue shitting because he's afraid that the turds will pile up so high in the bowl that they may make contact with his junk as it hangs down into the toilet. Much like the fingers of Adam and God on the ceiling of the Sistine Chapel.

Guy1: dude why'd you flush twice did it really smell that bad?

Guy2: nah man it was a Sistine Chapel Shit.

Guy1: ahh!!! I See.

Sistering

A condition where the male partner in a relationship clearly adores or is simply in love with their current partners sister. Given the opportunity all those diagnosed with this condition would instantly embark upon a new relationship with the sibling, at the drop of a hat.

"Ssup, dawg"?
'"I've been a twot! 20 years and I'm still sistering for Nettie. Poor Rene never stood a chance and she's a fucking shrew while I'm at it".
"That's harsh, Bred".
