This distance between a girls legs directly below her pubis symphsis.

(There is a slight distance decrease as the inner thigh usually bulges in, about 1-1.5" down from the perineal. This is natural in even the most perfect 18 year old specimens)

GAP TEST

Tell your woman to get in her bikini. Instruct her to stand in an upright and standing position, as if she was waiting in line at the grocery store with food that she will cook for you later tonight.
With her facing directly in front of you, make sure that her ankles are touching each other.
From her ankles to her crouch, the inside of her legs should never touch. Ever. This is the GAP TEST. If her legs do touch, you will need to consider taking drastic measures to remedy the situation.
Calling her fat will not help, add -ass to the end of it, that usually increases response time.

Also see The Bridge and The Valley to learn other important female attributes.

The Gap is the part between a womans arse. You can see their Gap with the help of tight jeans.
Damn, have a look at her. Tight Jeans, tight arse and The GAP.
Guys love filling a Gap and some box eaters with their plastic toys, you don't have to be a carpenter to fill it either.

In skater context:
Simply put: something you jump over on your skateboard. Could be anything. Traditionally refers to actual gaps or stairs.

Gaps can be anything! Use your imagination and you will go far as a gap skater. I repeat: gaps can be anything (that you jump with your skate board).
