Jabroni
A total poser who brags but can't do anything. A total idiot who always ends up getting embarrassed.
That guy is a jabroni. He told me he could beat anyone, and then he cried when he lost.
She calls me a jabroni every time I pass her in the hallway.
He said he was the best, but then he got beat up by a kid who wears socks with sandals.
