A'nnesia
A'nnesia is a person who thinks they're the best at everything and won't let anyone forget it. They're always giving people side-eye and talking about how much better they are.
"You think you're good at life? I've had more coffee than you've had problems."
"You think you're cool? I've been to more places than you've had friends."
"I don't need to explain myself. You're just jealous of my glow-up."
