Vacation debt 

The consequences that one has to face for taking a vacation.

The fatigue that you have after coming from a hectic vacation or the chores that you missed because you went for a vacation but needs to be tended now along with everything else that's currently going on.

Another example would be the work that gets piled up while you are gone at your workplace and now needs to be done along with the current work.

I can't make it to the party tomorrow, I'm still dealing with my vacation debt.

I need a spa day to get rid of this vacation debt.

I'm drowning in my vacation debt, oh, it's horrible.

grippy sock vacation 

A stay in the mental hospital. Name taken from the grippy socks given to (mostly involuntary) patients. Patients are not allowed shoes with laces due to suicide risk so grippy socks like those used at trampoline parks are issued to patients for footwear.
See: "psych ward socks"

Source: Was in mental hospital in 2019 and know other patients from other institutions

Phrase originally used within mental hospital circles and later spread on TikTok and other social media.

"If the professor gives us another fucking project, I'm going to need a grippy sock vacation!"

Vacationitis 

The lack of concern for any of one's responsibilities in the days (or weeks, or months) leading up to a vacation. Physical symptoms include the wearing of capris and jeans at work, flip-flops, or Uggs, and a lack of makeup or grooming. Dishes begin piling up in the sink, and the afflicted's response to most questions is: "Uh, I'll worry about that later." Can happen as early as the date of vacation planning, or as late as the hours before the flight leaves.

Yeah, I was going to wash my hair, but I figured I can do that once I get to Maui. Next month. I must be suffering from vacationitis.

Christmas Vacation 

The best thing that Christmas has to offer. No school for a decent amount of time while you relax with all of your new gifts you got! Also the title of the 1989 movie staring Chevy Chase.

Christmas Vacation is so fucking amazing, especially since I can now play all my new games.
