March 2018 as that meme had spread to non-meme kids, group clicking was a thing with it – whole classrooms and auditoriums of American kids clicking. Amazing phenomenon actually, although in a way not so different from other flash trends. My nephew thought it was just his class of course, but it was US wide by that point. [no idea about other countries].
Now it’s about at the rank of a minion. But it had its time.
