Elbow bumping.

[Workingman]

Does anybody do it except as a joke between family and friends?

<rant>I find it all a bit 'primary school' so I just give a nod and a smile and carry on.

Watching children and A-Z list slebs do it to show off how woke they are and how pure their social justice warrior qualifications are is one thing, but seeing world leaders at international conferences doing it makes me cringe.</rant>

Grow up!

exactly that - as a joke with my niece and nephew; usually followed by a regular hug
