A person playing a videogame or any sort of game online while at the same time drinking loads of RedBull and eating fastfood. It could also be used as a verb: "to tab". You could either be a tab or tab by yourself or with others, even though it is not a very social event.
Person 1: Evan is not going out tonight, he'd rather sit alone at home playing Halo and drink Red Bull.
Person 2: Ah, seriously? What a tab!
