Pacmoshing
Pacmoshing is when you turn into a fat, loud, hungry monster at a concert and smash your fists together while screaming OM NOM NOM and chomping people like they're snacks.
At the concert, I saw a guy pacmoshing so hard, he bit the guy next to him and didn't stop until he ran out of teeth.
My friend tried to pacmosh the crowd, but all he got was a face full of elbow.
I pacmoshed my way through the crowd and ate three people before I remembered I had a lunch.
