A slightly deformed young woman with profoundly wide jawbones.
Usually selected by a Dyke who operates in the background of a widely distributed women's magazine, she is selected to be on the cover and she will be recognized by having distracting eye and lip makeup.
Paradoxically, this distraction from her jaw deformity is attractive to (or ignored by) many normal, middle-class, female magazine purchasers, and such magazines profit well from the display of their osteo-warped models. Some even go on to become movie stars despite their handicaps.
Often classified as a fetish, the best explanation is that Dykes somehow are attracted to wide jaws in females as a faux masculine trait, and thereby acceptable where a genuine male jaw would not.
Good grief Herbert, gouge out my eyes! Look at that Cosmo Girl on the rack there!
