Get the simple bitch syndrome mug.
1. When someone knows the truth, hears the truth and sees the truth. And still continues to be dumb.

2. When someone is afraid of something that they don't understand. Refuses to understand it. Yet want to act as if they know everything about it.
Example 1.

Guy1. "I saw your girl creeping out of a hotel last week with another dude."

Guy2. "You're lying. My girl would never do that."

Guy1. "Look man. This girl is a hoe. Everyone sees it but you. You need to wake up." -shows proof.

Guy2. "Imma still be with her anyway. I don't care what you or anyone says."

Example2.

Girl1. "I can't fuck with someone with HIV. They can keep that shit."

Girl2. "You idiot. You act like it's airborne. There are people who live longer abd healthier lives wit the virus. Aids and HIV are not the same. They're more scared of you than you are of them. "

Girl1: " I studied it when I was in college. People can die from it. "

Girl2. " You can die from Aids, dummy. Not HIV. It can lead to Aids if not treated. God. You gotta be the simplest bitch on the planet. Simple bitch syndrome is real, y'all. "
