Like the word "Badasstic" only having a wider, more transferred semantic range of use.

Used in a video titled, “The Top Five Things With Which Jason Bourne Could Beat Your Ass” along with Badassery, Badassedness, Badassity, Badasstic, Badassitudinous, Badassitious, Mucho Badasstico, and Badassiticity
