From the viral song and music video "Friday" by Rebecca Black - remember the girl in pink who sits to the right of Rebecca in the car and dances awkwardly? She does a dance with her arms that looks like she is playing an accordion. This dance is called "The Benni".

A portmanteau of carpe diem, a Latin phrase that means “Seize the Day!” and DM, which stands for Direct Messages. This word means seizing the day via DMs.
