This is an animated gif of an extremely elated Arvind Mahankali moments after winning the 86th Scripps National Spelling Bee by successfully spelling 'knaidel', a Yiddish form of unleavened dough dumpling. Afterwards, the 13-year old kicked over the podium and flipped off the audience before climbing onto the back of the second place winner and yelling, 'GIDDY UP, BRONCO!' Or he might have just kept standing there -- he's a loose cannon.
Thanks to PYY, who informed me nobody should ever be able to take a confetti shower IN THEIR HONOR with a straight face. It isn't right.
