Simultaneously doing all bodily functions at the same time in a violent explosion. Including but not limited to: laughing, sneezing, coughing, hiccuping, blinking, farting, burping, pooping, peeing, popping a zit, sweating, having your period, acidic discharge, giving birth, lactating, sharting, hemoraging, salavating, vomiting, queefing, and ejaculating. Gigglyfloofing results in death 99.9% of the time. The only known person to survive a legit gigglyfloof is a Jewish Rabbi from Germany who was shot and killed two weeks later during the Nazi invasion of 1943. There are no know warning signs that a gigglyfloof is about to occur, except a sudden pause right before the explosion. Fat people are expecially prone to gigglyfloofs as they have extra pressure built up inside of them already.
