machood
A machood is someone who says they're cool but acts like everyone else is a nobody. They’re the worst kind of fake.
My friend said, "You're a machood for telling everyone you're cool but ignoring them when they talk to you."
My cousin called my brother a machood for saying he was the best but never helping anyone.
My teacher said, "You're a machood for being the loudest in class but not even paying attention."
