Bayou Butt Buddy

When you go to Taco Bell (or other diarrhea causing fast food) with a buddy on a hot day. Eat way too much and wait for you and your friend to get the sweaty, poop filled, "Bayou Butt". Then you go to town to clean each other with your tongue. You are now Bayou Butt Buddies.

Hey bro you hungry enough to go to Taco Bell and become my Bayou Butt Buddy after we're done at this orgry?
