Rapegoat

When a crazy ex-girlfriend has consensual sex with another man but claims she was raped in order to re-establish a line of communication with the ex-boyfriend.

Ex-Boyfriend: "I know she's crazy and I really don't want to speak to her ever again, but I only answered the phone because she said was raped last night!"

Friend: "I saw her last night and they were all over each other. She using him as a rapegoat so she can make you feel sympathetic and talk to you. Now you feel sorry for her AND she's fucking other dudes."
