It’s pretty common today to see a couple of guys give each other a fist bump in the office when things go well, but where the heck did that gesture come from? The fist bump started with pro boxers in the 1970’s, after people began imitating how they touched their gloves before a match. Later, the gesture became popular among basketball players, who would bump fists with their teammates instead of shaking their hands, to preserve the chalk on their palms. The gesture soon spread to all basketball lovers, and, before long, to the President of the United States. Yes, President Barack Obama has been known to enjoy a fist bump every now and again.
