Scheide.

You know how sometimes people get bored of saying the same thing over and over again, so they come up with new words to express what they mean?

Well, in German, "Scheisse" means "shit," and "Schade" means something like "Too bad."  And after a while, you get sick of saying the same things over and over again, so Antti decided he would combine them to come up with his own new word:  "Scheide." 

If you speak German, you're already laughing.  If you don't, keep reading. 

You see, it turns out to have the most unfortunate meaning ever.  Especially when you recall how many times you've said it out loud in public. 

We had thought it would be the equivalent of saying something like "Shite" in english; it's not really word, but people will know what you mean, and it's your own clever creation...

Nope.  It means "Vagina."
