Merda! The Real Italian You Were Never Taught in School.
by Roland Delicio and illustrated by Kim Wilson Eversz.

This booklet is funny and enjoiable, but it contains many linguistic mistakes.
As an Italian native speaker I'll help you navigate among those mistakes.

A cheap cunt = Una spudErata.
Wrong: it's a spudOrata.

A ballbuster = un/a rompAcoglioni.
Terribly wrong: it's a rompIcoglioni, gender-regardless.

Mentre studiavo I miei vocali (while practicing my vowels).
Horribly wrong: it's "mentre studiavo LE mie vocali". It recurs twice in the booklet.

A gossip, a chatterbox = Un Chiaccierone.
"ch" in Italian sounds like K: it's a Chiaccherone (pron. Kiakerone).

An airplane = Un aero.
It's obiously an aerEo, that thing flying in the sky...

The pilot of this plane is either drunk or half dead.
Il pilota di questo aero sarà briaco o moribondo.
again with the aerEo and the pilot might rather be Ubriaco with U (!)

Hey, miss, take a peek. Mine's thicker than this book.
Guarda, signorina, ce lo più grosso di questo libro.
Desperation: ce lo HO più grosso, meaning I'M ENDOWED WITH A BIG ONE (the penis).
"ce lo più grosso" might mean the opposite: that you're hiding your big organ rather than boasting its size as supposed.

You simpleminded wimp = Inalfabeto.
It obviously means an AnalfabetA (illiterate), just like the author.

Mi prude il culo: Grafiamelo. It's graFfiamelo (scratch my ass) with double F.

I nani mi divertono nel circolo, non ha letto.
Dwarfs amuse me in the circus, not in bed.
three mistakes in a single entry: circus is circo, not circolo which is a club.
"non HA letto" is mad: while it should apparently be meant to signify "not in bed", HA is a verb which makes it a surreal pointless "Dwarfs amuse me in the circus, HAVEN'T YOU READ".
Third and last but not least, making fun of dwarfs provides you with the tool to make yourself an idea about the author's idiocy.

Un "Inalfabeto":
