friendly mosh

A mosh where when someone pushes you, and you push them back, they turn and grin at you, like, "isn't this fun? we're in a mosh!" and you grin back in agreement.

Usually occurs at small rock concerts on college campuses, where most of the attendees are not real rockers.

Something venues say in order to forgo all liability in case someone gets hurt moshing the proper way.

A complete contradiction, because moshing is an untamed release of anger and adrenaline, and there's nothing friendly about it other than the common courtesy that includes picking someone up if they fall or helping someone out if they are injured. The only people who say "mosh friendly" are those who want to look like hardcore punks/metalheads but they're too scared to actually get in a real f**king pit. They're normally the assholes who piss and moan about how someone accidentally elbowed them.
