Adjective-
1. The excitement of
one's messed up teeth. Especially
one's teeth with post-oral surgery, that has resulted in no teeth at all.
2. Fantastic freak of nature, one with only a half
set of teeth. A beauty so unusual.
"Wow! That girl, sitting at the
piano has such a snagtastic
smile, I might have to let her give me a Chicken
Patty!"
