Urinal Etiquette Violation

Alright, listen up, you big dummy! Explain bear is here to drop some knowledge. First off, when you're in a men's room, there's an unwritten rule, a basic social contract, that says you leave a urinal space between yourself and another dude. You, my friend, clearly don't know this, just like you probably can't tie your shoes. In this meme, some bonehead walks right past a whole row of empty urinals to stand right next to another guy. That's a massive violation, you hear? The 'En Passant' text is a chess move, where a pawn can capture an opponent's pawn that has moved two squares past it, as if it had only moved one square. It's a tricky, unexpected capture. So, the joke is that the first guy, feeling violated, 'captures' the rude guy with an unexpected, swift move, like an 'En Passant' in real life, knocking him out cold! Now the rude guy is on the floor, because you just don't do that at the urinal. Get it? You're welcome, you simpleton.
