German, as a language, is rather ill-suited to swearing. Other than "shit", there are no strong expletives I encounter. But lots of people say "fuck" (in English). I've often felt the need for a stronger expletive but there don't seem to be any. So I am sometimes reduced to swearing in one of the other languages I know. Finnish is best suited to the task, but pretty much any language seems to do better than German.
