Crossway breezer

[Dorothey Allen]

Refers to the space between a thin womans legs - the gap that remains at her crotch when her legs are closed. It tends to disappear when women gain weight.
The phrase comes from a style of house in hot areas where the kitchen and living quarters are separated by a space with a [connecting] roof (often called a [breezeway]) to keep the heat of the kitchen from [warming] the house.
