saw teeth 

When you look at someone and they smile at you, their teeth appear to have a zig-zag formation.

"That bitch was fine until she smiled and flashed her scraggly saw teeth!"

When all of a sudden a girl says something that makes you immediately stop being attracted to her. To make matters worse then you realise what horrible teeth she has.

She said she likes rollerskating and then I saw her teeth.
