An aggressive expletive supplement to an obscene hand gesture (typically upraised middle finger) directed at someone the insulting party believes to be a heavy user of web-based computer services that feature "share this" links. An up-dated variant on the now-tiresome practice of withdrawing a hand from a pocket while simultaneously uttering, "I've got something for you," only to reveal the aforementioned obscene hand gesture.
While standing in a lengthy, pre-dawn line at an Apple Store that is rumored to have incoming stock of recently-released iPad2 tablets available, an individual at the back of the line objects loudly to a guy joining someone at the front of the line. The line-cutter turns to the objector, raises a middle finger and states menacingly, "Hey, dweeb, Share this!"
