Man this was a funny ass thread, just spent close to an hour reading the whole thing. That one where the guy farted and the other dude vomited is hilarious!
Anyways here is my contribution:
One of the gyms I frequent there are lots of stuck-up, rich, assholes who think they are god's gift to humanity. They steal benches all the fucking time, even when I got my straps and water bottle on or next to them. I'll ask them to let me finish up but sometimes they just act like they are really into their set and cant talk, and they drag their god damn sets out for 3 minutes, doing like 100 reps. Well anyways I have this problem on a fairly regular basis so I've come up with a nice plan for revenge. If I am laying particularly nasty farts and someone does that shit to me, I will intentionally hold a fart until it's real bad and then walk by the person that stole it and fart either right next to their face or just right next to them. You guys should try this shit, it's priceless to see the looks on their faces, especially if you are getting some of those raunchy protein farts. Some of the guys I do it to make such horrific faces....I mean the kind of faces that would make you think they saw their grandma naked!
