Get the headcasemug. A person that is impossible to date due to numerous psychological disorders, offensive personality traits, or unresolved psychosocial trauma.
When we first started dating, I was able to deal with his extreme passivity, unwillingness to drive at night, never wanting to have sex, fear of adhesive tape, and never answering questions about his personal life. I finally dumped that headcase when I found out his current roommate is his ex and they still have freaky bondage sex together.

My former girlfriend called me 3 separate times on my cell - back to back to back - while I was meeting with my boss, after each time I told her specifically I was with my boss. I was nearly fired. She was not right in the head; I don't care how good that booty was, because it was not good enough to deal with that headcase!
