I like to sit in the back of the bus because I want to see everyone's reactions when I rip out my farts
What motivated you to you even do that?
I enjoy the sensation of pinching my butt cheeks together and holding them in.
So you make them loud on purpose? You should not fart in an enclosed space like that, it is kind of rude.
What if I fart into my hand or hold it in would it be better?
Making it silent would be better because you are not loud, but you should try to hold it in before you leave the bus if possible.
