I will never hear or see this word again without thinking of this joke.      
           
           
       I was at my bank today; there was a short
       line.  There was just one lady in front of me, an Asian lady who was
       trying to exchange yen for dollars.  It was obvious she was a little
       irritated . . .
        
       She asked the teller, "Why it change?  Yesterday,
       I get two hunat dolla fo yen.  Today I only get hunat eighty? Why it change?"   
           
            
       The teller shrugged his shoulders and said, "Fluctuations."   
        
       The Asian lady says, "Fluc you white people too"   
     

I thought maybe she needed some gas-X.
