Haven't heard "I couldn't be assed to do it over here yet.
Not sure what you mean, McGrath, but "That's a real kick ass car" means a hot one with all the features (at least in the mind of the speaker). "He's a kick ass guy" means that he gets things done (used to be taking names and kicking ass, but the first part has disappeared). A sales team, or a football team, is told "to go out there and kick ass." I hope that it soon becomes a cliché.
