PCD stands for programmed cell death. This happens when a cell is in a state of poor health/disrepair, so release of special proteins (like cytochrome c - found in mitochondria) either from inside of the cell or by another cell, triggers an organized chain reaction of events, resulting in the degradation and destruction of proteins and nucleic acids inside the cell.
The genes responsible for the proteins that signal PCD are not working correctly in cancer cells.

Proper Creep Distance. Adj/verb. The appropriate distance at which you should walk behind an attractive chick. You should maintain this in order to get a good view but avoid alerting her to how hard you're staring at her fine ass and/or legs and making her run off like a spooked gazelle.

Post concert depression. That day or week after a much anticipated and amazing concert where you wonder how you're going to carry on now that it's behind you. Doing deep dives of the artist's instagram, twitter, youtube, etc. Looking for new shows. Showing everyone the crappy videos you took and them responding to your paragraphs with "sounds great". NO ONE WILL EVER UNDERSTAND

Post camp depression. The silence of my room is deafening. I stare at my ceiling all day with an empty smile from the memories which leads to tears and anger that I can’t just be there for one more day for the next 10 months. School friends don’t hit the same, no one cares to hear about inside jokes from the summer, I just want to see camp friends but they’ve all gone back to their own lives, probably suffering from PCD too. It doesn’t go away, it only becomes more numb as the memories and camp vibe become more and more distant in the past. Ok gn (aka try to sleep but just think abt my bunk bed)

PCD stands for Post Camp Depression. It is the feeling when you come back from camp and feel lonely, sad, and disappointed by how fast camp went by. It is also the feeling of missing everything and everyone that was at camp and missing the feeling of joy you had when you were at camp.
