1.Instead of saying "cool" or "sweet" one can say "sewt".
2.A Sewt is a person that is typing so fast on an Instant Messanger, or anything on the computer, that they are hurrying up to type to get in a word before the other person. The Sewt doesn't make sure they typed correctly, and came up with words that make no sense at all that no one understands it.
