You've got to ask yourself...

Who did YOU exploit today?

I proposition this to you: if you insult someone and then immediately ask for a high-five, not only will you get the high-five BUT the person will aslo be so dumb-struck as to overlook the verbal assualt.
or maybe it just works with kids?

Let's enact a sociological experiment. Turn to your neighbor/cube mate and try it out today!
High-Five!
