Shit-for-brains

That shit-for-brains assistant of mine lost my files again.

Who are you crying about, the predatory prick or the shit-for-brains tramp? Because neither one deserves your tears.

That new assistant of yours is a real shit-for-brains.

He's another one of those shit-for-brains.

Call your press conferences. Organize boycotts. Sue the shit out of me. You're gonna do for free what I would have paid you for, shit-for-brains.
