An abbreviation often referring to Facebook's uploading software found on smartphones. Self-obsessed Facebookers and J.A.P.py girls tend to love this function, as well as term.
Pictures can either be:
A) Hysterical: Large woman with a small shirt in public.
B) Whorish: Uploader sends mirror photo of him or herself before they go out partying.
C) Drunk: Blurry, out-of-focus photo that seems like a good idea when the Uploader is drunk. Often accompanied by a drunk caption.
