Can be anything, from characters not using objects they have on them, to physics not being realistic, or a very big plot hole.
As an example, one of my friends told me that his pet peeve is that in a lot of sci-fi movies, when spaceships run out of fuel, they stop moving, while inertia and lack of atmosphere should keep them in motion.
The bonk on the head to incapacitate. It always works instantly and has no long term implications.
Thief (The Dark Project) is one of my favorite video games of all time, but the instant KO blackjack weapon causes one of the hardest splits in play style in any genre of games. Using the magic sleeping stick, it’s fairly trivial to take out all the guards and have free run of the map. Not using it essentially requires some form of “ghosting” (beating the level without being seen at all) which is a significantly tougher challenge in many cases.
The prevalence of the trope certainly speaks to some deep inner cromagnon urge in us for problems to be solved with a simple “bonk!”

Characters in dystopian settings with clean faces with makeup, and perfectly coiffed hair. You’re telling me that whoever built your doomsday vault decided that a 10 year supply of concealer, mascara, lipstick, etc should be part of a survival kit?
This one is a bit more specific, but in the new dune movie, literally everyone just starts panting and heavily breathing through their mouth after any exhertion.
The fremen absolutely know better, and I’m almost positive there was a line in the first movie when they were explaining desert survival to Paul where they say you must preserve as much moisture as you possibly can so always breathe through the still suit
It’s an old trope, but still bugs me: Ordering food and leaving the table long before it could have arrived.
If you wanted to have a 5 second conversation, meet under a lamppost or something, not at a fucking diner!
It always bugs me when someone stands up, unfolds a few bills and drops them on the table. Then they just walk out. How do you know that’s enough? Maybe someone ordered some 32 oz margarita with top shelf tequila. Are they just leaving a massive tip? Or are they leaving a shitty tip and don’t want to look their server in the eyes?
