We feel awkward kissing each other because we’re not used to it and end up doing the ‘one or two kisses?’ dance, then accidentally touching lips with our friend’s granddad.

You don’t hug someone unless they are family (or you are a hippy) and shaking hands is too heartless and formal, like you were raised by butlers in the 1940s.

So, what do you do with pals you see 10 times a day, say, at work, school or college? You need to somehow greet them, then draw a conversation to a close, and a, ‘Hi… bye’ with your arms swinging seems a little wimpy.

That, ladies and gents, is where the fist bump comes in.

From the traditional handshake came the ‘gimme five’ palm slap that evolved into the high five and, finally, our fist bump. And when President Obama and Michelle Obama fist-bumped each other in 2008 it brought it to everybody’s attention. It has many names, but the ‘fist pound’ or ‘dap’, is not just for the youth and it’s definitely the future. In these germophobic times, it’s a more hygienic way of hello/goodbye-ing and it’s also a friendly but firm way of saying, ‘Step away now, I’ve finished with you’. All I know is I now find myself regularly bumping knuckles with at least four different male colleagues every day.

I think it’s becoming so mainstream that pretty soon we will see world leaders Bumping The Rock and the Pope will reach down to the crowds and bless them with a Fo’ Knucks.

Believe me… it’ll happen.
