Thanks for including my mistake as an official term now. I'm not the source, since I didn't give it any meaning. That was someone elses doing and s/he can keep the credit.
Honestly I don't think it funny to joke about peoples mistakes. What about the rest of you? I think my English is pretty good for someone who has never been to an English speaking country, but it's not perfect and I make mistakes. I'd like to see you write Finnish as well as I write English. Actually if you are interested I'd be happy to teach, since that's my future profession.
Edit.
I don't mind being politely corrected. Actually, I'd like it as I want to learn. But I don't enjoy being a laughing stock.
