Kachra fella
A person who’s like a trash can, full of nonsense, no value, and you can’t trust them for anything.
My cousin is a kachra fella. He said he’d help me move. He showed up with a bag of chips.
My dad’s friend is a kachra fella. He said he’d pay for my pizza. He said he’d pay for his own pizza.
My friend’s dog is a kachra fella. It barked at the mailman and ran away.
