A cute girl u think is normal and hook up with only to realize she is screwed up in the head. they are virtually undetectable at first glance. Red flags include; talking about her father when she is naked, weird fetishes, asking what number personality you are, if she tells you she is psychic or compares her psychic abilities to others, etc . no matter how hot she maybe be aware of the possible mental landmine that can/will ruin a perfectly good hook up.

B: Good Shit she was cute.
A: Nah, she started crying about her body issues and her horoscope halfway through sex. Totally ruined it for me.
