Bass 

A portmanteau of the words "Bad" and "Ass", pronounced like you would the instrument, not the fish. This word can just be used as a replacement for saying "Bad-Ass", so that it comes out quicker, and is not construed as being socially impolite.

"Dude, Batman is such a BAMF."
"Yeah dude, The Dark Knight was a friggin' bass movie."
