When a couple are having anal sex and the man is pleasured with an unexpected residue when withdrawing from their partner's anus. The "unexpected residue" is brown in tint, and usually resembles algae..
Damn bro, I was humpin this chick in her ass, but when I pulled out she gave me some fucking brown algae on my rubber. FUCK that bitch needed to wash her ass out.
Used to describe situations when an individual feels as thought he has to crap, but he hits the can and only long farts come out.
Bill Viverito, my personal bathroom attendant thought he was slick and tried to crap, but after a long delay it was determined that there was a sustained brown out.
1. Defecating inside a carefully spliced banana peel and resealing, leaving a suprise ripe for the picking.
2. When one carefully opens a banana peel and removes the lower 2/3rds of the fruit only to replace the bottom 2/3rds with feces after which he or she inconspicuously reseals the peel for eating.
My broke-ass friend ate all my groceries the last time he was over. This time I booby trapped him with a brown banana.
