Camel toe is a special fairly unknown term which refers to the female crotch that looks like a camel toe when women wear tight clothes. It looks like the letter w which likewise resembles the toe of a camel.
In order to have a camel toe, a woman has to wear very tight clothes and she also has to have large labia; only then a w-shaped camel toe can form in the crotch of a woman. The fabric of the clothes slips between the labia which makes the outlines of the primary female sexual organs visible. Clothes that abet the formation of a camel toe have a stitching in the middle like hot pants and jeans.
