A Buffoon's Buffoon
A total nobody who thinks they're a rockstar. They’re just a loud mouth with no talent.
My cousin’s friend is a buffoon's buffoon. He tried to rap in the grocery store and got thrown out.
My neighbor’s kid is a buffoon's buffoon. He tried to do a karate chop on a pizza and it fell apart.
My brother’s teacher is a buffoon's buffoon. He wears sunglasses inside and talks to the ceiling.
