Packing Ass
A phrase heard in the halls of a school, used to describe a guy who gets his jollies by looking at butts.
Kyle Uniacke was walking through the hallway and said, 'Packing Ass,' and the whole school laughed at him like he had a badge of shame.
That guy in the cafeteria keeps saying 'Packing Ass' every time he sees a new lunch tray.
My friend said 'Packing Ass' in math class, and the teacher gave him a pop quiz for being too distracted by the butt of the girl next to him.
