makes my ass hurt
This is an adjectival expression best used to describe people, places, things, moments, and events that are so annoying/stupid/ridiculous/grating that
patience diminishes, moods deflate, and the threat of violence increases. Basically, this phrase can be used to describe anything or anyone that grates on your last nerve.
The fact that we are having a departmental meeting to discuss cover sheets and TPS reports really makes my ass hurt.
