A person in a leadership role who abuses their "power" to overwork, underpay, undermine, etc their subordinates in the most unethical way. They usually do not belong in their role as they haven't had any formal training and just ended up their by sucking the dicks/tits of their former superiors. Everyone who works underneath them hates them openly but the piss rat's ego doesn't even recognize this. (see also, narcissist)

Get the Piss Ratmug. A derogatory term that describes Eshays with red hair. With the word "Ranga" being the abbreviation of orangutan while the "Rat" means that the person is poor/homeless. Usually only used in Australia.

Get the Ratmug. Nancy was an absolute blub rat at the club last night. I had to put down my manual on extension cords just to take in the madness.
