When a chick crams herself into a pair of jeans and the crotch area has to displace the fat of her mound and the front of her pussy ends up looking like the actual toe of a camel.
My four year old turned around really fast and ran into this chick's camel toe, when he turned back around he had a hoof print on his forehead
A very aesthetically pleasing phenomenon, whereby a woman's venus mound is clearly discernable under the snug fabric of her lower garment. Typically, the fuller the labia, the more pleasing the effect. Tip: since sexual arousal causes increased blood flow to the genital region "toe" may be enhanced if she finds you desirable:)
