UNFUCKWITHABLE 

The pinnacle of one's self confidence, not allowing anyone to put you down or disrespect your honor, and being who you are and showing it without fear of being taunted or disrespected.

Boy 1: That boy killed himself?
Boy2: Yeah, he was getting bullied by this unfuckwithable guy, just couldn't stand up to him
Boy1:That's harsh
Boy2: Yeah, if only he was unfuckwithable, no one would mess with him. Too late.
