Your character(s) have been invited to a Rock or Metal concert:
So, what kind of concert goer are they?
Have they ever been exposed to this kind of music?
_What do they do while there? _
How do they act?
For reference, here's a couple comedic videos as some context if you've never been to a metal show.
Now I'll do my two characters from the above picture.
Rip:
The Enthusiastic Show Bro
At the show, Rip is the kind of guy who's up against the stage and doing as much as possible. He sees a pit, mosh or circle, doesn't matter, he's in it.
He goes for the mic if the singer holds it out, even if he doesn't know the words.
He smiles at everyone, and is so enthusiastic about each band playing, he does all the cues, even if he's never heard of them.
When in the pit, he hits the hardest, but he also picks anybody up that falls, or he knocks down
After a band's set, he's up there congratulating them and then moves on to his fellow concert goers, and is as friendly as possible, giving out high fives and sweaty hugs.
Rip's the guy that is kind of annoying, but by the end of the show, he's got about 10 new friends, because he's having so much fun it's infectious.
Freya
Crowdkilling Pit Ninja
Freya's the one that gets kicked out by security first. She's relentless and aggressive for almost no reason.
She hardcore dances with reckless abandon and kicks as many people as she can.
She stagedives feet first into the biggest person she can find.
She's there to start a fight, not really for the music. Look out, because the pit hasn't started, but that won't stop her.
