Habitually Offended
A person who can't stand being ignored so they make up fights with anyone just to get a reaction and scream about it like it's the end of the world.
I saw a guy yell at a barista for not saying 'hello' properly.
She got mad because her friend called her 'dumb' once and now they don't talk.
He started a fight with a pizza delivery guy because the crust was too big.
