I feel that this new trend is, at least, ridiculous. Many videos of it uploaded in my news feed on Facebook recently and yet, are more to come. Youtube has a large number of videos relevant to this.
I have seen one-two videos of it and to me, there are some bunch of people, dressed in a -supposed funny way- ridiculous way and -supposed to be dancing- doing some strange moves, with some -supposed music- playing on the background.
Students of my university, are going to make one on Friday, inside the university, inspired from other universities around the globe (Toronto's and more).
First gangam style and now harlem shake. Is the ridiculous always selling? :/
