Already Taken Disqualification

Someone who is already in a relationship and is not eligible to hookup with or get with you and/or them.

Jason: Is your ex texting you again? I guess he's already heard that you broke up with your boyfriend.
Charmaine: I think he's trying to get drafted during Transfer Season. For some reason he's ignoring the Already Taken Disqualification.
Jason: That guy's got a bad case of CharMania. I could see him wearing a t-shirt with your face on it!
