If someone’s cool, they’ve got style and they’re relaxed. If something’s cool, everyone likes it.
■ For example:
- Gillian’s new boyfriend seems like a really cool guy.
- Hey, check out this site for learning English. It’s got lots of cool stuff like games and blogs – and it’s even got a totally cool section on slang!
Note: This word has been a slang term for a very long time and, like blue jeans, it never seems to go out of style. It’s still one of the most widely-used slang words.
