People (almost exclusively males) who spend a large amount of time adding random girl profiles on facebook, myspace, bebo etc, for the sole purpose of gaining access to their picture sections. These people often take the time to create new e-mail addresses and new profiles with different names in order to remain anonymous. Once they have been accepted as a friend the person will look at every picture in the girls profile while masturbating. This person also searches for profiles which are not set to private as it makes their blog humping a whole lot easier.
"Hey man, just a word of warning. If your girlfriend sees a friend request from Mike on her facebook, tell her to reject it. That fag's a blog humper."
