A real chip on your shoulder. The state of feeling like your shit dont stink. Originally derived from the adjective, pompous, or the noun, pomp.
Did you notice the pompacity of that hoe? Just cause she's got double d's doesnt mean she she can walk around acting like she dont like suckin d's. Makes me want to give her a Japanese Hari-Kari Avalanche.
The art of behaving with a lack of class and elegance due to an super-inflated ego, causing one to respond to other non-pompous people in a condescending manner. This phenomenon appears to be much more common in middle-aged women.
