Reference to a high maintenance person, usually used in response to a demanding, needy, or high maintenance request. Lets the person making the demands know that they are being high maintenance, without directly saying so. Can be used in the third person as well, to assert that someone was being high maintenance or demanding. Refers to the fact that the demands and neediness make it "all about me," with "me" being "my ass," similar to phrasing such as "his ass better hurry over here" or "my ass will not be attending that party."
In response to, "I need you to come over and put my laundry in the drawers because I just did my nails, and I don't want to mess them up," one would say "Well, look at my ass!"
