A euphemism for a hangover. It makes the user of the term seem a little more sophisticated than if they simply said: "I have a wicked hangover and puked all over the place". It's also humorous in that it makes the person with the condition seem like a world traveler rather than a sloppy drunk.
"Hey you look out of it"

"Yeah, I really have a bad case of Jet Lag this morning"

A messed up sleep pattern due to late night studying. Especially among University studentswho study during the night and then get up early for lectures or exams just to fall asleep during the day when they get home. Adjusting after several weeks of late night studying back to a normal sleeping schedule is usually difficult and the student experiences a jet lag even though they haven't been traveling through time zones.
Dude, I can't fall asleep at night, all that exam cramming has given me study jet lag
