The appearance a woman's anus and vulva make when she's bent over nude. It is further enhanced if the woman's butt cheeks are spread open.
Dude, Debbie was teasing me last night and I totally saw her keyhole when she bent over for me!

when a bullet fired from a gun strikes its target at a funny angle, the resulting asymmetrical hole looks like a keyhole, hence the name. usually caused by a worn or damaged barrel, or poor quality/incorrect caliber ammunition.
that ancient pistol i inherited from my grandfather is so worn out, half the time the bullets will keyhole and the other half of the time i can't even hit the target.
