machood
Machood is a person who's always messing up and still thinks they're perfect. They're like a kid who breaks every toy but still thinks they're the best.
My sister said, "You're a machood for spilling your juice on my new shirt."
My dad said, "You're a machood for burning my dinner again."
My friend said, "You're a machood for failing math and still thinking you're the best."
