You can go to the urban dictionary, for heaven's sake.  It's right there, it means "I was just fooling."

And it's an old phrase.  I'm 59 today (whoopee) and I've heard it on the street for decades.

Have you know moral sense?  Or is it all support your candidate no matter what he does or says?

So you don't care that Obama got in on the demeaning of women?

I guess not.
