Never cried over a game but really there's nothing wrong with a man crying. If anything, it shows strength to do so in public or admit to it, anyway. Why? Because the inevitable reaction is 'oh you're just a puss.' Well, obviously not because you're not afraid to let it all hang out and make yourself a target for abuse. A lot of guys are so scared of showing emotion that they hide it behind being stoic because they're terrified of getting emotional and that ain't brave at all.
Now crying over everything or things that really shouldn't matter to you or anyone is a whole 'nother issue. But there's a difference between crying over things that are by their nature emotional and whining.
