This is the expression used for the type o' guy who has to pay for repairs on the tank that just hit him, the guy who uses helicopter blades when shaving, the world record holder for most lead eaten in under a minute, the guy who's faster than a crack head with a prescription pad, the very same man that had Chuck Norris mow his lawn, the kind o' guy who catches his taxis by hand and the one we all know as Ultimate Badass.
"Wow! That guy just pimp slapped that polar bear!"
"You mean Stephan? Yeah, he's Ultimate Badass"
