A brief exchange of the words "What's up?, Sup?, Sup man?,etc." when passing by someone you know but would not otherwise stop and engage in heavy conversation with.
Alex: Sup?
Me: Sup man?
Later that day I tell my friend I was talking to Alex.
Friend: Oh what was he saying?
Me: Nothing. It was just a suptual exchange.
