<human>: Can you summarize the given text in a few sentences?

A little bit of backstory, so my friend Micheal is a heavy dip user, he has been since I know him, and he's a pretty rad guy. But anyway, for those that don't know, you're supposed to shake up dip before you use it. So me and my friend Micheal are chilling in the school bathroom, doing what teenagers normally do in the bathroom, and he says to me "I really gotta shit, wanna shake this up for me man, I really can't hold it" so I oblige and take the can and I start shaking it up while Mikey Boy does his shit-jig. This is were the FU starts, so I'm shaking this WHILE facing the urinal, so no poor soul who walks in the bathroom will see what I'm shaking. But as soon as a start shaking the dip, a fellow classmate walks in and I hear a *blood curling* scream and the dude runs out, before I can explain what I'm doing, so Micheal rushes out and I explain it to him. After wards we walk to class, and as soon as I get there, the whole desk that the guy who saw me in the bathroom is giving me the stankiest eye ever. Needless to say, I was quiet the whole class
<bot>: Shook up a friends dip near a urinal, someone thought I was choking my chicken, got the meanest stank eye from classmates, whole school probably thinks I fucking spank the mank on the down low
