A combination of the words Bad ass and Fantastic for the resulting: Badasstastic. Used in the same context as "beast", "sick", "steezy", "greasy", etc.
John: "Dude, you'd never guess what I did today!"
Steve: "Oh, I dont know, what?"

Steve: "Thats pretty Badasstastic, but I have a life."
Something that is totally awesome.
Seeing my favorite band live is badasstastical.
