A few characters use filthy language on Y/a. Are they a step ahead?or they think they are too smart?

Filthy language originates from a part of the brain that is not consciously controlled, whereas ordinary 'intelligent and meaningful' language requires processing power........Go figure.

I tend to think that the use of "filthy" language indicates either an adolescent desire to shock or a limited vocabulary.

That means that you know Spanish, because english has no filthy language.

Well, they are very annoying people, but you report them and yahoo does NOTHING. That is even MORE annoying

They are about 10 steps behind, and are not very intelligent.

They're children who think using bad language makes them sound grown-up.

Good question! may be after this question, the number of people submitting such languages would be highly reduced. and eventually it would come to an end. good work, keep it up.

I don't think its any of the two reasons you have mentioned. its simply because they have grown up using that language. & they consider it no offence.

a step behind

I agree with AnArdRi.

There is problem in their blood.
