the sum of jet-lag-like symptoms caused by watching a series of matches (e.g. the FIFA World Cup) live, in the small hours of the night, due to major national time differences, over a period of days or weeks (with "net" referring to the net in soccer, or tennis, or volleyball, etc.)
There are still two late-night World Cup matches to watch! Football has caused me a lot of very late nights this month, and I'm blooming knackered, suffering from an acute case of "net lag"!
