J-hoo - A kid who still thinks they're cool until they hit 49 and re

A kid who still thinks they're cool until they hit 49 and realize life is just a series of bad decisions and worse hair.

My cousin is a J-hoo. He still thinks he's the king of the school. He's 48. He's still stupid.

My mom called my dad a J-hoo. He was 47 and still had a mullet.

My teacher said I'm a J-hoo. I'm 13. I'm not even close to 49. She's a J-hoo too.
