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.
