US Slang Expressions

[junediamanti]

Some weeks ago, I generated a bit of discussion over English 
expressions.

Now I'm turning the tables slightly.  I've always greatly admired 
the American ability with slang - it's smart rather than dirty or 
rude and seems to be a direct descendant of wisecracking humour.  

What are your personal favourites - I'm not really looking for 
swearing here, more kiss off, smartass type remarks.  Anything that 
you find particularly funny, smart or amusing.

Be creative.  Exercise your living language skills and prepare to 
astonish me!  Ethnic imports are not only allowed but positively 
welcomed.
