Casual games and hardcore gamers, easily. People use "casual" to describe games which are not at all casual. A casual game is one designed for short play sessions over a very long period of time, months to years.
Hardcore gamer isn't even a real thing. It's more or less a pretentious term certain gamers apply to themselves to try and elevate their status, because they don't like admitting to being a couch potato.
Another one is "athlete" that certain gamers like to call themselves, to make themselves sound like Michael Jordan instead of Poindexter.
I also think genre labels are abused.
People use "First Person Adventure" to try and dignify an FPS over others.
People will use "RPG" as a label to action titles, this is mostly true with certain Nintendo fans who wanted to play RPGs, so instead of buying them on another platform, they just decided that Zelda and Metroid are RPGs instead.
The use of "open world" as a label for non-open world games just because they have a big map.
I even saw a video recently that called Super Mario Odyssey a sandbox game like Minecraft and Dwarf Fortress.
On this forum "Bold prediction" - again, just a pretentious euphemism when it should be: uneducated prediction.
I describe myself as a little dose of toxic masculinity.
