Nadeau effect
Someone who walks into a room and immediately makes it worse. You remember them like a bad dream. Everyone else thinks they're cool, and you just want to throw them out a window.
That new kid at school is the Nadeau effect. He talks like he’s in a commercial and nobody gets it.
My brother’s friend is the Nadeau effect. He eats hot dogs for dinner and thinks he's a king.
That guy in my class is the Nadeau effect. He wears socks with sandals and everyone claps for him.
