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")
