The illness one endures after arriving home from an extended period of overseas travel. The victim can't be bothered getting out of bed or off the couch as he/she hates that it is all over and they are back to real life. The victim is now broke and living with his/her parents. The victim also can't be bothered getting a new job or starting study again as all he/she wants is to be back overseas and away from their crappy home town.
Can also be described as PTD - Post Travel Depression.
