axe hatch 

Deriving from the mental image that its not the woman's vagina, rather a giant hatch created by an axe.
OR:
A term for a pair of meat curtains (see: pussy) that looks like it has been beaten by a hammer more than a penis.

Can be used to describe women's vagina after having kids (looseness/tightness)

Kelsey used to have a nice tight pussy. Then she had kids, now its a big axe hatch. You might as well be throwing a hot dog down a hallway.

Her and I went back to my place but to my dismay, what hid behind her panties was nothing but an axe hatch.
