A
woman who possesses co-dependant traits and is both possessive and controlling with regards to the men she dates. The male gender'
s underlying assumption is that said
woman's boyfriend remains in this unhealthy relationship due to the sexual gratification the female provides, specifically, fellatio.
A common turn of phrase pertaining to this is "He's being whipped", which means that the person in question is being dominated or controlled, historically represented by a whip, which was used to drive slaves.
When a man dating a
woman with whip lips has his
girlfriend/wife overtly make a controlling gesture or demand, verbally or otherwise,
friends in or near the occurrence often make a whipping sound, such as *Wha-chu*, immediately after said girlfriend is out of earshot to denote the fact she has whip lips.
Also jokingly referred to as Whipelipsy, a play on the disorder known as Epilepsy.
