selfietitis
a new, emerging infectious, psychosocial disease in which the person inherently takes pictures of himself in front of the mirror or in public places that the person continuously takes several or hundred shots of selfies for several hours until he finds a suitable shot for himself to post or display in a social media network. Spectators tend to imitate the similar poses and actions causing infectious behavior.
