From the terrible feeling you get when someone uses teeth during a blowjob.
My boss just told me I have to work this weekend. That's pretty teethy.

Teethy-Girl
A woman that can be identified just by looking at her teeth (Covering her face and just displaying the teeth).
Examples of teethy-girls include Lady Gaga and Yvette Gonzalez-Nacer from the Fresh Beat Band. Both are very beautiful, and nothing is wrong with their teeth, but it's easy to identify them when just looking at their teeth.
The world is filled with many teethy-girls. Just look around and you will see.
