Beefed up rats that are likely to be found in corners of maps and head-glitching. Often cause rage in good players.
In rage I screamed "MEGA RAT" at the lil bitch soy boi camper in the corner of the map in a video game.

Get the Ratmug. 
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)
Employee 1: "I don't like my boss Rachel. All she does is blame everyone else for her frequent errors."
Employee 2: "Classic Piss Rat Rachel"
