Bonnasses (fr.-engl.)
"young and beautiful real life girls, mostly above the age of consent; not necessarily nude, photographed in sexy and/or compromising positions"
A marathon bong session where everyone brings their own stash. The last person left conscious wins the bongathon, and as a prize, gets to drink the bong water.
I think I won last night's bongathon, but I don't really remember drinking the bong water.
