Gremlish
Sometimes you get pearls of germanified english, such as the following:
You have already used all available Mailinglisten. To get more, you have to update to an extensiver product.
Well, since there exists a word for the same done with japanese, “engrish”, namely, I propose henceforth to use the term “gremlish” (being one of the only pronouncable mixtures of “german” and “english”; as well as referring to little critters doing mishap) for things like this.
It’s not exactly Mock German but something produced by (somewhat) english-speaking germans who either apply german grammatical rules to english texts, or who use german words in an “englified” form in english texts. Hence “more extensive” may become “extensiver” or “mailinglists” may become “mailinglisten”.
