A Treasure's Trove
A person who acts like they’re the king of the world because of one stupid thing. They don’t care about anything else. They live in a fantasy world and won’t come out.
My cousin is a treasure trove because she still thinks she’s the best at Pokémon.
My brother won’t stop talking about his YouTube channel. He’s a treasure trove.
My mom’s obsessed with her hair. She’s a treasure trove.
