Cheeks to the wind

Cheeks to the wind describes the act of a woman going to the toilet outside. Aptly named because of the fact that your butt cheeks are literally exposed to all the elements as you squat in the least ladylike manner.

‘Yo where’s J-Lo?’
‘She’s behind that car, cheeks to the wind’
‘Jeez dude it’s snowing’
