When I was in high school there was a rumor going around my gym that some bodybuilder was benching 600 and his balls exploded from all the steroids.
My best story: girl is deadlifting on the platform, I walk up to her and ask her how many sets she has left. Wasn't flirting or anything, pulled one earbud out, asked the question, her response with a disgusted face: "I have a boyfriend, he's here." Ok, that's fine, I'm thinking, some people, you know? I say "Ok cool, but I need the platform, are you almost finished?" With a very annoyed sounding "ugh" she turns away from me and starts deadlifting again.
Ok fine, I wasn't gonna bother arguing so I went to do my usual warm up which takes about 30 min. Now I come back, half an hour later, and she and her boyfriend are WAITING for me at the platform. They're not using it, they're waiting for me and she says: "there he is". "Fuck my life" I'm thinking. The dude walks up to me and says: "my girlfriend told me what happened, you got a problem dude?"
Now this guy isn't huge or very intimidating, but he was damn serious about whatever the hell his girlfriend told him so I casually said that I just asked when she would finish with the platform and she told me she has a boyfriend and that I really don't care. He then says: "you're gonna fucking apologize to her" and I say (and now I'm getting irritated) "excuse me? for what exactly?"
This guy doesn't give a fuck he now shouts "apologize" and pushes me causing me to stumble on the platform. Now I'm not about to beat a kid in the gym so I shove him back, not hard, but just hard enough to cause him to fly back into one of the biggest and hardest looking guys in the gym.
His name is Stephan. And now Stephan is very angry that some random kid just bumped into him and caused him to knock his shake over. And now him and his girlfriend are trying to make excuses and blame me for everything, but little did they know I gave Stephan a spot a while ago and he's one of my boys. So he shuts them both up and tells them to promptly remover their rears from his sight. He must've cussed them out for like a good 2 min.
Moral of the story: keep your cool and make friends with the big, mean guys.
