In English, people often say ‘what’s up?’ instead of ‘hello’ or ‘how’s it going?’ when
meeting someone they know well.

For example:

1. Hey, bro! What’s up? I haven’t seen you for a long time.

2. What’s up with you? You look just like you’ve seen a ghost.

3. Can someone please tell me what’s up with the photocopy machine?
Did you get it?

See you soon!
