YOU are 

spoken with emphasis on the "you"

is the lowest form of comeback to an insult, usually, but when used correctly (e.g. out of context) it becomes one of the funniest and most classy calls

usual context:
bully "you are so fat, look at you, fatty fatty boom boom"
kid "you are"

used correctly:

Jason "this office is a bit sterile without a radio"
Brendan "YOU are"
