Flatulist

A flatulist is someone who can make funny noises with their bum. They can fill their bum with air and then squeeze it out to create funny sounds like farts. It's like blowing up a balloon with your bum and then letting the air out to make a silly noise. Some people find it funny and entertaining, while others might think it's gross. Either way, being a flatulist takes practice and skill. Remember though, it's important to respect people and their bodily functions, and not to make fun of them for being different.
