Got bars? adidas Originals is inviting you to prove just that with their new “Drop A Rhyme” campaign. Coinciding with #UniteAllOriginals and the launch of the new Run DMC collection, Instagram users can upload a 15-second video of themselves rapping over the A-Trak beat from the new commercial. The best uploads will be chopped up into the official #UniteAllOriginals remix. Watch the video below for the steps on how to participate and start uploading on IG now.
