New Word Suggestion
Lalochezia
The use of foul language = Submitted By: SukhJug - 23/08/2012 - Approval Status: Pending Investigation
and
lal·o·che·zi·a (lal'ō-kē'zē-ă), Emotional discharge gained by uttering indecent or filthy words. Farlex Partner Medical Dictionary © Farlex 2012 via TFD

As additional information, English has a grand tradition of "inventing words" - often "nonce" words for a particular set of circumstances: Few of these ever make it into the language. e.g. 15 Words That Don’t Exist But We Definitely Need Inside Our Vocabulary.
And then there is the Book "The Meaning of Liff" which is a dictionary of words that don't exist.
