P-bag
A P-Bag is a guy who wears pants so baggy they look like a sleeping bag. He probably sleeps in them and eats pizza for dinner.
My neighbor is a P-Bag. His pants are so baggy they’re like a tent.
He walked into class like a P-Bag. Everyone laughed at him.
He called me a P-Bag. I said, 'At least I don’t look like a sleeping bag.'
