Scores of Iranians across the world have been busting President Trump's signature dance moves in viral social media videos after US-led strikes wiped out Supreme Leader Ayatollah Ali Khamenei. Footage of Iranians pulling the so-called "Trump dance" has been exploding online in the wake of Saturday's deadly strikes -- with some hailing the dictator's killing as "the best day of my life." The celebratory clips captured people dancing and singing along to the "YMCA" as they mimicked the staccato arm movements made famous by Trump at his rallies.
