The feeling you get after loads of hours on LAN parties. You feel cold even though you are sweating and hot. This is most likely caused by either all the bad food you've eaten, all the energy drinks or just staying up for a while.
After 24 hours of LAN'ing:

John: Damn, maybe I've caught the flu! I'm feeling so cold even though I'm hot and sweating.
Peter: Mate, you've got the LAN-cold.
