A woman who is adept at using sex to subvert, manipulate, and ultimately control the man she is with, in order to get what she wants. This us usually done through the promise of sex, though the aforementioned sex may or may not be (and in most cases isn't) delivered.

A vagyrant will usually prey on desperate,lonely, or genreally weak willed men who have the inability to think with anything else other than their dicks.

Men who fall prey to a vagyrant are inevitably turned into panty waste pussies of epic, eunuch-like proportions.
"Our buddy was supposed to go to the strip club with us tonight, but the vagyrant he's living with made him stay home to paint her toes."

Get the Vagyrant mug.
The sexual movement of the woman's lower body in a way that could make any man want to scream. Not just lazy pole dancing but a full on gyration of the vagina.
Last time that girl vagyrated I proposed to her and she was just a hooker.
