Bak

Comes from bak (back at keyboard). You can name a person just like that when he shows signs of anti-social behaviour. The worst case scenario is that he will find family tables as an excuse to avoid going out, despite that he will be playing video games all night.

He rejected my invitation and didn't come to my party. He is so Bak
