A book that has become a cultural phenomenon as the female version of "He's Just Not That Into You". It is basically a list of pet peeves or turn-offs that women have against men. The book is divided into three parts: things men wear, things men say, and things men do. There are over 300 items listed and while many of them seem like legimitate complaints, others seem downright petty. There is a rating scale for each to measure how much of a turn-off it is which range from minor (red flag/storm cloud) issues to more serious (not getting any/kiss of death) ones that can kill any chance at romance. The book can be found in the humor at section at local bookstores and while it does offer some good advice, men should take it with a grain of salt.
A man who owns a reptile, clips a cell phone to his belt, and uses catchphrases is considered undateable. A man who does anything feminine such as wear makeup or drink cosmopolitans is considered undateable. A man who doesn't pay on the first date or doesn't leave a tip ensures that he won't get a second date.

Describes an individual so flawed that they cannot possibly be dated by anyone.
Mandy: Phil is so completely undateable. I have no idea why my cousin set us up.
Tamara: What happened?!?
Mandy: For starters, he is 35 and lives with his parents, and he smelled like rotten vegetation. And there were nose hairs.
Tamara: Agreed. Undateable.
