A rat bastard is the lowest form of a deceitful, backstabbing, and downright rotten human being. This isn’t just your run-of-the-mill jerk—it’s someone who actively schemes, manipulates, and betrays, all while pretending to be decent. A rat is a snitch, a sellout, a traitor who turns on others without hesitation. A bastard, in this context, is a dishonorable, remorseless scumbag who has no loyalty, no principles, and no problem screwing people over for their own gain.

A rat bastard doesn’t just step on people to get ahead—they enjoy it. They’ll smile in your face while they’re twisting the knife in your back. They’re the kind of person who lies without blinking, takes what isn’t theirs, and leaves destruction in their wake without a second thought. No remorse, no guilt, just pure self-interest wrapped in a disgusting, two-faced package.

If someone’s earned the title of rat bastard, they didn’t just make a mistake—they made it their whole personality.
