Ever since Guardians of the Galaxy hit theaters last month, audiences quickly latched onto fan favorite Groot—particularly when it came to that mid-credits scene. It’s already sparked fan-made toys (since Marvel has yet to provide official ones for fans to throw their money at) and edited dance-offs. And, thanks to GotG co-stars Michael Rooker and Dave Bautista recreating the scene at Wizard World Chicago Comic-Con, it’s created the term and phenomenon known as “Grooting.”
Marvel’s already encouraged fans to make their own Grooting videos, and GotG director James Gunn—who actually created the dance in the movie—is even leading large crowds in the sneaky dance craze (including someone in a full-blown Groot costume).
Gunn and his brother Sean showed up for an interview at Dragon Con, and with a large crowd of cosplayers behind them. Everyone knew what to do from there.
