kachra
A total waste of space. They talk way too much and do nothing. They're like a broken robot that just blabbers nonsense.
My boss is a kachra fella. He talks for an hour but can't make a decision.
My friend is a kachra fella. He asked me for money and then forgot about me.
My cousin is a kachra fella. He promised to clean my room, but it's still a mess.
