Fridging is a common practice in comics and general media where another character exists to die or be hurt for the sole purpose of furthering another character's plot. Though the term was originally coined by Gail Simone in 1999 as "Women in refrigerators" (In reference to a plotline where the green lantern found her newly introduced girlfriend sliced up in a fridge) though it may still refer to the same mistreatment of female characters, it has become less gendered over time and the definition has become less niche to involve somewhat characterized cast members as well as new ones.
Some prominent examples of fridging include:
Uncle ben
every single character to date deadpool
every single orphaned characters' parents
"I don't know why I still read comics, every single one ends up fridging a character."
The seemingly contaigous diseast that effects employees on Fridays. Symptoms include not showing up for work or even calling in, usually triggered by nice weather. Home cures include golfing, taking a trip to the shore or sleeping late and going shopping.
Half the plant is out today.. I think they're suffering from fridayitis.
The act of searching the fridge continuously but not eating or drinking anything in there. For example, when you get home and just keep looking through the refrigerator and cupboards but not grabbing anything to eat.
"Hey, Kitty, what are you up to?"
"Nothing much, just fridging."
