57. Crossing paths with a vagina dentata
As Seen In: Teeth (2007)
Every hookup in writer-director Michael Lichtenstein's disturbing 2007 horror-comedy Teeth will hurt male viewers especially, considering that Dawn O'Keefe (played sweetly by Jess Weixler) has a rare case of "vagina dentata." And, yes, that means exactly what you're thinking: Her genitals are packed with chompers.
Those private teeth can't help but bite off the joint of any guy who upsets her during sex. Which happens more than once in Teeth, but never more sickeningly than the sequence in which Dawn thinks she's bumping uglies with a decent guy, for a change, only to find out that he's just as scummy as the next soon-to-be-dickless fella. See, it pays to be nice.
