boo pipes
I was playing "Mario Kart Double Dash" on the GameCube and I unlocked a car called the "boo pipes" and that day I had a serious case of ass gurgling,soooooooo put name and action together and got "the boo pipes" - Internal farting/gurgling. When you have it you must exclaim "I have a serious case of the boo pipes!"
When your sitting on the bus and your ass implodes, and everyone looks at you thinking it was your stomach, but you know better.....
