Brown Boxer 

This is what you call a fart that usually ends up causing you to change out your underwear.

Adam: "Hey Josh, that fart sounded so loud just now. That is not appropriate for work"

Josh: "Not only is it not appropriate, I think it was a Brown Boxer too....I gotta go!"

A brown boxer is when you take a shit and it’s so long it hits the bottom of the bowl then slaps your nuts

Full Blown Boner 

The event horizon of any gathering (social or private) at which the fun and excitement of the moment is bigger or more exciting than usual.

Guy1: "Dood, that party last night went Full Blown Boner right after you left with that Swamp Donkey. There were so many more hotty-bomb-bodies than guys that some of them ended up hooking up with each other!"

Guy2: "STFU..."
