Packass
A person who’s got so much stuff in their back pockets it’s like their pants are doing the work for them; they’re like a walking storage unit with a face.
He walks in with a sandwich in each hand and a bag of chips in his pocket. Packass.
That guy’s back pockets are full of junk. He’s a packass.
She’s got a pen, a phone, and a snack in her pocket. Packass.
