Using your fart to blow a bubble with your bubble gum. Usually happens when under the influence of mind altering substances. Can be a form of foreplay at teen parties.
Zach was trying to impress Gabi at Tyler's party when he decided to to a Carolina Fart Bubble. After several failed attempts, two blue flames, and buring Roy's eyebrows off. Jared showed Zach how it was done using Bazooka gum. This caused Britanny to want to do it in the dugout the next softball game, but Jolene chewed all the gum. Robert and Thomas were so excited they wrote a song about blowing bubbles with your ass.
