"give me five" and "slap me five", any difference?
The difference is only one of expression and context, not meaning. "Slap" me five is a funkier way of saying "give me five" or "give me some skin" or any of several ways of asking for a hand slap/slide.
OK. You all must be too young! "Slap me five" was a term used in the 60s and 70s, when one person put their hand out in front of them and the other person slapped their hand. It was a gesture, like a greeting. A "cool" way of saying "hello." Probably more common in urban or inner city settings. "Slap me Five" and "Give me Five" meant the same thing.
