Story example: I tried to let out a huge fart on my friends face while he was sleeping, on my final push it came out, along with a huge stream of piss. When he woke up, I told him, another friend in the room parted on him. He got pissed and beat him up, later he found out it was me and beat me up too. So in other words, dont try to fart in your friends face or it might turn into a part and you'll end up getting your ass kicked.
Other guy: Oh man dude thats hilarious!
