madddog
A person who can't even be annoying properly. They're like a bad joke that no one wants to hear.
My brother is a madddog. He tried to be a rapper. Now he just sings in the shower and no one listens.
That kid tried to be a superhero. He wore a cape and tripped over a dog.
He said he'd be a millionaire. Now he's still broke and living with his mom.
