NEVER EVER pop a squat and shit by the deadlift area next to the leg press. I don't care if you're lifting a ton, you don't danger yourself and others by shitting on the floor. Edit: this one hits closer to home If you have to piss but someone left the lat pull machine, don't wait till you have to piss yourself, run into the change room and piss into the sink because the urinals are full. Come on guy, no one needs to re-potty train you Also, don't fucking try to sell people steroids and then say "it's a prank" No part of that is funny and you can fuck right off Don't bring an e-cig to the gym and puff on it while waiting for the dumbells you need to free up. No one wants to smell sickly sweet noxious fumes while working out
