The phrase became famous through Insomnia, the 1995 dance single by British electronic group Faithless, where vocalist Maxi Jazz delivers the line in a weary spoken style. The track became a major club hit and its central hook stayed closely linked to sleeplessness in popular culture. Online, the short vocal excerpt was later shared on its own as a reaction sound for late nights and exhaustion. Its lasting appeal comes from how instantly it sums up being awake when everyone else is asleep, without needing any extra explanation.
