Jacknose
A jacknose is a loser who smells like old socks and thinks they’re cool. It’s the worst insult you can get, and it’s like being called a human trash can.
My mom called my cousin a jacknose because he ate the last slice of pizza.
My friend’s teacher called him a jacknose after he fell out of his chair.
I told my brother he was a jacknose because he tried to kiss my dog.
