Yeah, of course!! Its used a lot :)

Hi! Yes, it's a pretty common expression. Here are some examples: 1) - We can leave later. - I am cool with that. 2) - Hey, if I ask your sister out, you'd be cool with it, right? 3) -Would you be cool with dropping by the post office on the way there? - Sure, no problem.

In the United Kingdom this is also used in casual speech. It just means you do not have a problem or objection to something. "I think we are going to meet at 5:00, what do you think?" "Yeah, I'm cool with that!" "Are your parents cool with me staying over tonight?" "Yeah, they don't mind!" Hope this helps!

In the United States, it is used amount the millennial generation to mean “Is it okay if...” for example: “Would you be cool with going to the store with me?” “I’d be cool with eating at this restaurant.” “Would it be cool if you dropped off that item you borrowed today?” If you’d like a class focused on slang and informal speech, book a class with me!
