You good? (can mean 10 different things)
I saw this online... and it's SO real. American english slang.
You good? - Are you alright? (question)
You good - You are ok. (statement)
You good - How have you been?
You good - Did you get enough?
You good - You're welcome
You good - Stop talking to me
You good - No need to say sorry. It's fine.
You good - You need some money??
It's all about the tone. But trust me, when you get it right, people know exactly what you're saying. Facts.
