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")
