No, not the kind you get from a Slurpee. The kind you get when Shihan tell you to lead the taiso and the name of the first exercise is gone. Erased from the memory banks. You know what the exercise is, how to perform it, but the name is irretrievable.
Not as bad as forgetting how to breathe, though. I did that later when Shihan was demonstrating how to get that extra zing in a nikyo.
