What's the difference between, "you've gotta be kidding" and, "you R joking"?
(Make sure to capitalize the beginning of your sentences and put commas (,) before quotes of phrases/sentences.)
"You've gotta be kidding" usually expresses exasperation, and often includes "me" so that it's, "You've gotta be kidding me!"
Example:
Bob had been expecting the homework to take an hour. He works for an hour and still isn't finished. He keeps working, after an hour and a half he looks through what he still has left to do and finds he's not even half done. In exasperation he exclaims, "You gotta be kidding me!"
/"You R joking"
I suspect this is meant to be, "You're joking!", ie, "You are joking." And expresses incredulity, that the speaker doesn't believe something that someone has just told them.
Example:
Jane: Bill just started dating Wendy
Bob (for whom the news is a surprise): You're joking!
Hope this helps! (and works in context xD) Cheers.
