Cool (adj) like awesome means ‘great’ or ‘fantastic’. It also shows that you’re okay with an idea. Be careful the normal meaning of cool means a little cold so you have to listen to it in context to understand what’s being said.
Example 1)
“How’s the weather in Canada these days?”
“It’s getting cooler. Winter’s coming!” (This is the literal meaning a little cold)
Example 2)
“What did you think of my new boyfriend?”
“I liked him. He seemed like a cool guy!” (He seemed like a nice guy).
Example 3)
“I’m throwing a party next week for my birthday. Do you want to come?”
“Cool! Sure, I’d love to!”
To be beat (adj) In normal terms ‘beat’ would be used meaning ‘to win’Manchester United beat Liverpool, or ‘to hit’ Marko, stop beating your brother, however, in slang or everyday English it means something completely different. If you hear your friend saying I’m beat, it means he or she is very tired or exhausted.
Example 1)
“Do you want to go out tonight? There’s a cool new rock bar that’s just opened.”
“Sorry, I can’t. I’m beat and I have to wake up early tomorrow.”
Example 2)
“You look beat, what have you been doing?”
“I’ve been helping my dad in the yard all morning.”
To hang out (verb) If someone asks you where you usually hang out, they want to know in which place you prefer to be when you have free time. And if your friend asks you if you want to hang out with them, they’re asking you if you’re free and want to spend some time together. And what about if you ask your friend what they’re doing and they just answer hanging out? It means that they are free and not doing anything special.
Example 1)
“Hey, it’s great to see you again.”
“And you. We must hang out sometime.”
“I would love that. I’ll call you soon.”
Example 2)
“Paulo, where do you usually hang out on a Friday night?”
“If I’m not working, usually at the diner across the road from school.”
“Cool, I’ve been there a few times.”
