In German humour, Manta jokes (German: Mantawitz) is a joke cycle about the Mantafahrer ("Manta driver"), the male owner of an Opel Manta, whose name usually is Manni (short for Manfred), who is an aggressive driver, lower class (typically from the Ruhrpott), macho, of lower intelligence, and infatuated with both his car and his blonde hairdresser girlfriend.
[1] He always drives with his elbow sticking out of the window (which is why his car's door is always rusty from the underarm sweat), his car is always lowered, tuned and decorated with a foxtail on the aerial and a "Kenwood" sticker on the rear window.
His education level is generally at most limited to Hauptschule, where he may have had to repeat several classes, and he likes to use interjections "Ey" and "Boah".
When speaking to women, he shows extremely direct flirting behaviour ("Ey, ficken?").
Jokes poke fun at a stereotype of the working class owner of a second-tier muscle car, typified by the Manta.
