A large, public, often overcrowded place of amusement that is (temporarily or permanently) closed off to all of the general publicexcept you and your party to enjoy alone and without lines.
The act of flaunting or showing something incredibly valued or sought-after (often video game prototypes) but not releasing them to the public. The name is in reference to the South Park episode "Cartmanland" where Eric Cartman has his own fantastic amusement park in South Park, but nobody can come except him.
"Look, everyone! I own the 1997 Spaceworld Prototype of Legend of Zelda: Ocarina of Time! How cool is that?"
"Wow! That's incredible! This is quite the video game holy grail! I can't wait to play that after it's been dumped!"
"Oh no, I can't do that. It'd ruin the value of it! Gotta keep it one-of-a-kind, you know?"
"Dude, what? Don't be a Cartmanland! If you don't preserve it, the cartridge will rot and then nobody will have it!"
Term used for when someone gatekeeps their own creation, and refuses to release to the public, only showing footage and not the actual creation itself.
Person 1: C'mon man, why don't you wanna release the map? It looks cool!
Person 2: Nahh, i don't really feel like it.
Person 1: I swear to god, stop cartmanlanding!
