In online role playing games, a sleeper is a character created by a player that is soon abandoned by its player. The character technically lives on in the game world but never speaks, works or interacts with other characters because its player no longer plays him/her. As a result, the character is often deemed a "sleeper" by the active characters and ignored until he/she succumbs to starvation or some other form of character death in the game or less commonly the player has a change of heart and decides to start playing the character again.
This is how it usually goes.
A character named Argon is born or spawned into the game world.
Argon: "Hello everybody what can I do to help out around here?"
Random character: " Argon, we could use a guard to help defend the city, maybe a blacksmith."
Argon: "Okay, sure."
One or two weeks later.......
Random Character: That Argon fellow hasn't spoken in two weeks. He made a hammer and then fell a sleep. He's a sleeper sojust let him starve."

Fans of games made by indie developer Project Moon that will appear almost anywhere if one of their triggers is said or featured otherwise, examples include but are not limited to:
Red mist, name of a prominent character
Ideal, prominent theme for a story
A black mask covering someone’s entire face, a reference to another prominent character
Despite Project Moon having a statistically smaller fanbase compared to larger fandoms, sleeper agents will arrive in large numbers almost anywhere if any trigger is detected.
The name Project Moon sleeper agent comes from the fact that these persons will activate a set of behaviour when specific triggers are triggered like any sleeper agent and are fans of Project Moon, therefore Project Moon sleeper agents.

Person 1: Grr I’m so angry at person 2 I’m going to turn them into a fine red mist.
Sleeper agent 1: Bait used to be believable- holy shit is that the Red Mist.
Sleeper agent 2: The red WHAT?
Person 3: Oh the Project Moon sleeper agents are here.
Sleeper agent 3: Everyone get in here: summon a limbillion Project Moon fans

A type of car guy with a normal, stock looking car (like an everyday person would have), but the performance of it is intense; simply the undercover of the car community.
These people will
1. Focus on all go, no show.
2. Hunts down rich douchebags in their supercars, who brags about it being "faster"
3. Modify their car's performance (Turbo, Intake, tires, etc)
4. Be the most unexpected when law enforcement gets included

The imbecile in the Ferrari 360 is to late to realize the Volvo 242 with the roaring V8 was a sleeper car
