When a bunch of men hanging out together simultaneously get a hardon. It can occur, for example, when a hot chick passes by them, or if they are watching porn together.
Guy 1: Dude, that girl was hot. I couldn't help getting a hardon from her.
Guy 2: Me too.
Guy 3: Me three. Looks like we're have a groupon.
