Photobombing

The Urban Dictionary defines photobombing as "an otherwise normal photo that has been ruined or spoiled by someone who was not supposed to be in the photograph." In a nutshell what is happening in the background attracts the focus from what it was originally meant for. Like most things in life it isn't as easy as it seems. Good photobombing requires skill, practice, good timing, a fair bit of luck and above all a desire to ruins somebodies special moment.
