vagteeth
refers to a really nasty and scary looking and smelling vagina, complete with the requisite unshaved bush and meaty flaps, which makes the guy think that it might have teeth if one's penis is introduced to said vagina. It could also pertain to a mean-spirited woman with control issues and constantly seeks to usurp and undermine her male partner in numerous ways, thus rendering his manhood null and void, ascertaining to her being a man eater of sorts.
I hears she's the one wearing the pants in the relationship since she always bosses him around wherever they go - probably has vagteeth bro.
