Parlez-vous Saint Gillois ? Spreekt U Sint-Gillis ? is a project about the spoken language in Saint-Gillis, developed by Constant Association for Art and Media. Between 2013 and 2015, they collected words with a special Saint Gillis character : neologism, hybrid words, inflections, loanwords, and other kinds of extraordinary language that found a new home in this neighborhood. They now published this vocabulary and other activities they did in a booklet under the title "Do you speak Sint Gillis ? Parlez-vous Saint Gillois ?", downloadable here.  You can find more information about the project here.
