1) A light cuss word in Germany. It directly translates to "shit", but in southern Germany kids will say it and not get in trouble. It really only means "crap".
2) An
americanised way of spelling "sheiße", since the double s is hard to understand for most non-Germans and is hard to type on an
american english keyboard.
3) A Lady Gaga song. Very surprising because she isn't German and she literally doesn't know a living fuck about
pronunciation.
