assie

The ass-view version of a 'selfie'

A photo of a person's ass, taken by the same person in the photo. It is then posted to Facebook/Instagram/Twitter to show everyone how good is your ass looking, and to make their friends feel depressed about being a flat-ass and worry about physical condition.

'Cara changed her profile picture last night, did you see it?'

'That assie without pants? Yeah I saw it... nice ass'
