The Black Speech of Mordor.
One that is clearly understood.
Japanese is cool as ****
Parisian french :D dream!
English, in an upper-class British accent.
French, everything sounds so sexy even if you can't understand it.
Second would of course be body language, its universal. A naked woman provokes the same thought in most men, regardless of what spoken language they speak.
Spanish. Duh. ;)
SEX! It needs no words and Yet it is understood by all!
French, followed by Italian.
Yiddish and Italian, equally
Im not exactly sure if this is a language but.. Irish accents? :) i <3 them
The one where you don't speak.
English, the rest sounds like gibberish to me
