when a moment occurs in ones life in which they have, or wish they had a camera, to take a picture of what is taking place...only in turn to upload the picture and set it as their default picture on facebook, myspace, twitter, etc.

Guy 1: Dude i look so jacked in this mirror
Guy 2: Oh shoot...so do i
Both: This is a default moment!!
