1.
A temporary disruption of the body's biological clock experienced by persons who stay awake all night chatting on the Internet to someone resident in another time zone (typically a person they have never met and never will). The effects of net lag, which may include fatigue and irritability, generally disappear soon after one's partner discovers the conversation history in the messaging application.
"Damn Taylor, you look like shit today."
"I know, that Swedish chick is giving me a severe case of net lag."
