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.
An unusually attractive girl with a quiet personality that doesn't catch your attention at first, but has men melting when she decides to speak up and get noticed. Usually an understated girl in glasses who doesn't wear make-up. Thus, just when a man thinks he's sized her up, she snags his attention during the double-take.
"Dude, did you meet Amanda at the partylast night?"
"That girl in the corner, nah dog, I didn't even notice her."
"Pshh. That's cuz she's quiet. Look again, that fine specimen be a Snaggleton."
