Diku
Diku means a MUD built from the DikuMUD codebase, or more loosely a game that feels like that classic DIKU-style text RPG lineage.
People use diku in retro gaming and MUD circles as a shorthand for a specific code family, design style, or old-school feel.
It is usually neutral, slightly nerdy, and instantly legible to longtime MUD players: if someone calls a game "a diku," they are tagging it as part of that warrior-thief-cleric, stock-zones, classic text-world tradition rather than using some random internet acronym.

What People Mean When They Say Diku
At the core, diku points back to DikuMUD, the influential 1990s multi-user dungeon codebase that shaped a huge number of text RPGs.
In actual use, it can mean either a game literally derived from that codebase or a MUD that strongly resembles the DIKU formula. That is why you might see it used almost like a genre label, even when the speaker is being a little loose with the technical details.
Where You'll See Diku
This word mostly lives in MUD forums, retro MMO discussions, dev chats, and hobby server communities. You are more likely to see it in a post comparing codebases than in a general gaming meme thread.
Socially, saying diku reads as old-school insider language. It signals that the speaker knows the history of text MUDs and can tell the difference between DIKU-style games and other branches like LP or Circle-derived worlds.
Examples You'd Actually See
That server is basically a diku with nicer writing and less grind.
I logged in and immediately got old diku vibes from the class list and stock zones.
If you want heavy quest scripting, don't start with a diku codebase.
When It Sounds Forced
Sounds right: I miss old diku servers where the classes were simple and the world felt dangerous.
Sounds forced: He left me on read, total diku behavior honestly.
Is This Still a Thing?
Yes, but it is niche. Diku is still understood in MUD history, codebase, and retro text-gaming spaces, though it is not active mainstream internet slang.
Outside that world, most people will not read it correctly, and the old "Do I Know You?" expansion does not have strong support as an established slang meaning.
Related slang around this usage includes 6-the-dollar.
