A person on Youtube (or likeminded websites) who submits a comment for the sole intention of getting "thumbs up".
Many of these people copy other thumbs up comments to get their attention fix.
John: Justin Biebers dick is as small as the dislike bar, thumbs up if you're listening to this in 2011
Jane: God John, you're such a thumbs up whore, the worst of all attention whores.
