When you eat too much spicy food and take a shit..... When your asshole hurts.
I had a huge fucking burrito with a ton of chile. Tonight I will have an angry asshole.
The opposite of, "resting bitch face" but for men who look mean, angry or frown a lot.
Wife: Honey you shouldn't frown so much.
Husband: Why, whats wrong with frowning?
Wife: Because it gives you Angry Asshole Face!
A very angry little shit, much like the evil human eating aliens from the critters movies.
It doesn't have to necessarily be in the physical ball form
or a midget but what would seem like an angry little bastard who reeks of rage and uncontrollable annoying anger.
Sid: Are you chicken shit? Come on man, you gigantic shit for brains! Come on come on!!
Giant guy sitting at bar: I am going to ask you nicely to please be quiet, sir.
Sid: Aww girly panties not pulled up? waah waah
I'm gonna head butt your abdomen and use it as my pillow!
Giant guy sitting at bar: Well, I think we need to take this outside because you're being a huge Angry ball of asshole.
