Gossip is conversation that's light, informal, and usually about other people's business. It can be fun to gossip about others, but no one likes it when they're the subject of gossip.
You can find people just about anywhere who love to chatter about the latest rumors and stories: they're gossips who love to gossip. You've probably seen all the celebrity gossip featured in the tabloids: stories about who's dating, marrying, divorcing, or having a baby. But don't trust everything you hear — gossip isn't always accurate, and often people spread untrue gossip just to mess with someone they don't like.
