Wallbombing
A new trend on Facebook, where various unsuspecting friends have their Walls bombarded by a prankster friend, who copies their profile pictures and tags them. The person who has his/her wall “bombed” by another is encouraged to retaliate, with friendly fire, duplicating as many elements as possible or desired for the imitation-photo (WITHOUT photoshopping) and posting back to the “attacker’s” Wall. The most vital goal of this operation, of course, is to get the facial expression just right.
