A large, scary tooth that pertrudes from ones gums and tries to latch on to anothers. They are super contagious so if anybody with a snarltooth tries to kiss you run away as fast as you can screaming "SNARLTOOTH" as to alert others.
Lord of the Rings characters, Disney employees, Dragons, etc. "Look at that snarltooth on that Flik's employee!!! RUN!!!"
That crooked tooth that makes that cute guy or girl even cuter, adding character and charisma. Also the crooked tooth that makes the person you dislike even more horrible in appearance, making you cringe or shrink away.
(Sigh) Tom's snaggletooth may seem like an imperfection to others, but to me it's irresistible.
A girl without a single straight tooth in her smile. Her teeth are crooked like a dogs hind leg and usually spaced pretty far apart. At least one or more of the front snaggleteeth are usually missing.
Damn, did you see that chick's grill. She's a fuckin snaggletooth tiger.
