It's like hello but it means bye. You say that to your closest friends when you have to leave but don't want to do so.
Kai: please don't leave!
Adrian: I really have to. Sorry man. Bello.
Kai: bello to you too.

It just simply means disgusting. You can use it especially when you feel extra disgusted that even saying the whole word is just too disturbing.
