Native speakers use this word all the time in casual English. Sometimes we pronounce the word as “Chillin”
It means something like “relaxing” or “doing nothing”. Someone who is at home and “just chillin” it means they are probably surfing the internet or watching TV. They are just doing some simple activity and nothing serious.
Friends often say they are “chillin” when they are together.
An example sentence is, “I had a few friends over last night and we pretty much just chilled”.
Here is a real native conversation:
Ted: Do you have any plans tonight?
Tom: I dont’ know. I’m not really in the mood to go out tonight. I’m just chillin at home right now. You can come over here if you want.
