Yeah that's fucking retarded, maybe the smell of shit helps with the duck lips expression lol
One of my pet peeves as a guy is when I'm taking a piss at the urinal and another dude rocks up to the one next to me and starts chatting away. Dude I don't want to have a conversation with you while we're both holding our dicks wtf lol
It's etiquette, you never use the urinal next to someone unless the place is full, and if you do, you shut the fuck up dude.
One disgusting thing I've noticed quite a few dudes do is not wash their hands after they finish their business. Not even a superficial splash of water, just straight up zip and out.
