After a discussion with @kassco410
I've see that it's a one main form of slang sentence
this is a fuck stuff
or this is a bitch stuff
or this is a shit stuff
fuck, bitch, slut and shit are the amplifier the level of the nervosity
of the character who speak, or his belonging of lower_class people
you know, if you translate directly in french the resultat is
ceci est une Foutue d'automobile / fuck
ceci est une putain d'automobile / bitch or slut
Ceci est une automobile Merdique / shit
The problem, in French , all word in a sentence must be turn in slang
because it exists one slang word for each normal word
And I can translate this one in English
