I've got no problems standing cheek to jowel with other blokes taking a piss, how else are you supposed to piss at footy games? Wait for a cubicle? f**k that, cubicles are for shitting or shagging, piss in the urinal unless you haven't got a dick.
About the only thing thats off limits is obviously checking out other blokes tackle or even worse commenting on it.
And what is with guys who f**k up the cubicles? not flushing properly, blocking the bowl with tons of paper, pissing on the seat (I mean WTF? lift the seat, or piss in the urinal you girl!)
