This is a characteristic often found in people who generally lack motivation and smoke copious amounts of marijuana. Nerb behavior is often defined as lazy, slow, and a lack of emotion.
Matt was such a nerb today, all he did was smoke and fall asleep on the couch while everyone else went out to the bar.
