Category for small mouths?

I recently saw a provider that while attractive, had a very small mouth but lots of large teeth.  The entire time she was blowing me, I was worried she was gonna clamp down as it was a very, very teethy bj.  It's an experience I don't want to repeat.

Now, we have acronyms and nicknames for all kinds of activity in this hobby.  For example, one might say that little 'spinner' did 'bbjtc'.    This lets the hobbyist know it was a thin petite lady that finished him in her mouth.  Maybe he has a preference for a different type but with this description, he knows what to expect.

So what about ladies that have small mouths with large teeth?  You know, like Pat Benatar.   Maybe we can use "PBs" for short.    Of course to make it more specific and true to the origin, so like Pat Benatar, a PB should not only have a small mouth with big teeth but also a great ass.

So a reviewer might say something like "Yea she's a nice PB so don't bother with the bj and just go for the greek."

I think this is something we should consider.
