A Dumb Bitch is that girl who is just wrong and think's she is right. She is that girl who is annoying and everyone think's she is this stupid annoying girl, but she is completely oblivious to everyone's complaints. She's that girl who will go out of her way to over exaggerate and attempt to make herself look cute when she actually looks like a stupid skank. She's crazy and no guy will take her seriously. She's that girl who makes you shake your head. She is that dumb bitch.
"Hey, I heard Jane Doe hates you."
"I've never even met her, I don't even know what she looks like. What a dumb bitch."
*shakes his or her head*
