Yes it is!

Our geography teacher is totally paranoid - if you use parasite words all the time, she lowens your grade! I mean, what do they have to do with geography??:rolleyes

But over here we have words like "nagu" - "like" and "vä" - "or" that are the most used parasites. Of course, some people have "kurat" - "damnit", their parasite. Right now, I don't remember what mine was... hmm... haven't talked to my friends in a while, I guess.
