Assjacket
Similar to the idiom, "Wear Your Heart On Your Sleeve" but instead of expressing your emotions freely, you (or someone else) show how much of an asshole you are.
Cal: Yeah, so I punched him in the face for taking the last slice of pizza.
Rudi: It was his birthday, assjacket.
Rudi: It was his birthday, assjacket.
