sleeper

In car terms, a sleeper is any car that only has performance modifications and no visual mods. AKA "All bite and no bark"

A sleeper is the complete opposite of a ricer.

(Btw, the sleeper here is the 350Z Driver)

Ricer: "LOL, look at that 350Z. It suxxx. Mah Civic is better in EVERY WAY POSSIBLE."
Z Driver: "I see you're challenging me to a race."
Ricer: "Yo, imma show yo the real power of zis Civic. We race. And I shall win. I'm serious."
Z Driver: "Don't even try. I've got more important matters to attend to--"
Ricer: "YOU SHUT UP! WE'LL RACE, AND I'LL WIN, AND I KNOW IT."

-a little while later-

Ricer: "Goddamn it! YOU N00B! GET BACK HERE FOOL"
Z Driver: "No u."
(Z Driver drives away doing the "lol internet")

Sleeper

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."
