Here's an idea: how about you humble yourself and ask the "fucking dweeb" next to you what he's doing in regard to his OHP? Perhaps you can learn something new and valuable.
By the way, if you're going to the gym mainly for the purpose of checking out other girls' asses, then I don't think you have the right mentality for training in the first place.
I don't go for that express purpose but - by example;
There's this chick comes in with her boyfriend/husband - and makes a point of immediately getting in my space, doing deadlifts, ass first in front of me - shit like that.
I imagine it's unquestionably to make her man jealous - cause, initially I was checking out her ass, sure.
But now I'm like, "just leave me alone dammit".
Her husband goes out of his was to say hello to me and chat a little - make sure I'm not actually about to creep on his woman - which I understand; even respect - cause I'd do the same in his position.
By further example - there's this other chick - younger - comes with her dipshit boyfriend.
He's like, an undesirable - but she's of the age where she must think that's cool (yes - that young; like, 18 maybe).
She pulls much the same stunt - but her dipshit boyfriend actually tries to act tough with me, throws me dirty looks etc.
Point being - at one point I thought it was boss, or maybe even funny, to flirt with other dudes girlfriends.
Now - I wish I was never so foolish to think that cause - it draws unwanted attention; and my time would be better served picking up single women, not chicks that I might bag, but whom are letting me, just as a means to fuck with their boyfriends head.
Which is a pretty lame reason to be hitting some chick.
