A gif of one man holding up his drink in a gesture of approval before four men standing behind him start clapping. Obviously, this could be used whenever somebody online says something that you agree with.
This particular scene is from a Wiserhood TV commercial. After being asked to hold his girlfriend's handbag while she goes into a clothes store, the guy takes out a plastic bag and wraps it around the handbag so that he doesn't have to hold it (or get seen with it). As soon as he does this, he hears clapping. He looks over, and the guys in the gif above are clapping at him in approval. "Welcome to the society of uncompromising men."
