"An XXX Parody" on each of them. I'm not native english speaker, but shouldn't there be "A" instead of "An"? Correct me if I'm wrong.
In English, an X can takes on the Sound of a vowel.
the AN is always used when it precedes a Vowel sound.
XXX stands for x-rated as in pronounced 'Ex'-Rated
and In that Instance, the X has a Vowel sound, as it has the 'Ex' sound
so AN is correct for
An X-Rated Movie
or
An XXX movie
An XXX Parody = An X-rated Parody
the use of AN is correct.
Counter point.Some people think of the XXX as = to Triple X
so in that case
a XXX movie = a Triple X movie
the se of A would be better.
But I think more, XXX = X-Rated so again the use of AN
Edit:
Ok Sorry
