kick in the ass

1. An occurence, remark, reply, or otherwise any given situation which genuinely causes momentary distress or disdain to the point that one tightens his or her sphincter, as if preparing to be kicked in the ass. (Also spelled using hyphens, like so; Kick-In-The-Ass, so as to accentuate that the phrase is to be used, or acknowledged as one word.) 2. Literally, a kick in the ass.
