A Frog with Pockets
Same as 'stick up his ass.' It means the person is a grumpy, stuck-up, ass-wipe who thinks they're better than everyone else.
My brother is a frog with pockets and a stick up his ass. He thinks he's the king of the world.
That frog with pockets has a stick up his ass and a chip on his shoulder.
He's got a stick up his ass and a frog in his pocket. He's a mess.
