When you come back to school or work from your vacation and you can't remember what you did before your vacation.
Andy suffered from a bad case of vacation amnesia when he went back to school and couldn't remember what he had been learning before.

Get the vacation amnesia mug.
when you go on vacation and have a miserable time, (a big family fight for instance), and about a week after it you can't remember the fight or anything bad that happened and start planning the next family outing talking about how fucking epic it will be to get all 6 brothers under one roof!!!

1) Jim to his bro. Dude, I can't believe our golf weekend turned into a UFC house and Bill lost 3 teeth and the hospital trip!!!

Bro to Jim- Dude wtf are you taking about!! that vacation was epic and I was looking forward to the trip to Vegas!!!
