a fart held too long that goes back up ur ass, up ur spine, into your brain and gives you shitty thoughts.

A fart produced from the pressure due to holding a fart in for an excessive period of time. Makes the sound g'burgle. Sensations include feeling like your stomach will explode and extreme bloating. Always occurs in the presence of others.

when you hold a fart for too long, and it finally pops inside your body before seeking its way outside. and after some time it slowly seeks out of your anus with a decayed smell that smells like old fart. (eg, could be the smell of a dead animal thast been dead for ages but still has not been cleaned up..)
