When someone did something that's radical or amazing:
-Dude! You are a total "fushnigit" for doing that radical stunt!
-I don't want to see your "Fushnigiting" face on this "Fushnigiting" town. "Fushnigit" you man! Don't you dare touch that ball or else I willbeat the "fushnigit" out of your "fushnigiting" face.
Warning: A lot of confusions might occur when using this word. Always remember to let the receiver of sentence know whether you're using the word as a compliment or as an insult. (This warning's not really necessary...they would probably know if the word's used as an insult or not depending on the situation).
