(informal) An extremely lazy person. If someone is a
lazybones, they will sleep past the morning, always be disorganised,
stay up late when they have school or work the next morning, never get their homework done, always make up silly excuses, never cook anything by themselves, and
play games too often.
What time did you get up today?
I
got up at 10 in the morning.
WTH?! You are the laziest person I've ever known! I get up at 6 in the morning at the latest,
lazybones!
See him. He never gets any of his homework done. He's such a lazybones.
