A deliberate change of sleep pattern with the intention to shift one's peak energy level toward nocturnal activities. Experienced especially after several consecutive nights of drinking and dancing. Etymological origin are the words "jet lag" and to go "clubbing".
Three days after school started I still had difficulties getting up early in the morning because I was still suffering from a severe club lag.
