Swedish Words

In Sweden we have some words that you really can't translate to English.  One of those words are "lagom", have you heard it before? It's means not to much and not to little, it's lagom.  Another word is "fika", wich basically means to drink some coffe and eat cookies and cinnamon buns.  And then there's "orka", wich means that you either orkar or inte orkar, meaning to choose if you have the energy to do someting or not.  There is probably more words but I can't think of anything more right now.
