Bush isn’t only an actress-activist extraordinaire. As the self-dubbed inventor of the air hashtag, she’s also a savvy social media influencer.
“Many years ago at one of the many nerd conferences I attend … I was speaking to the founder of Twitter,” she explained during an appearance on The Tonight Show with Jimmy Fallon in 2014. “And I was like, ‘#happening,'” the actress continued, while using her air hashtag gesture. “And he was like, ‘What did you just do?’ And I said, ‘You know, some people will air quote, like it was ‘awesome,’ and when you want to air hashtag you do down, to the side — there’s your pound sign.'”
While host Jimmy Fallon was quick to bring up the popular air hashtag bit he’s done on his own show, Bush jokingly argued that hers was better, saying, “Mine only takes one hand and you don’t have to say ‘hashtag.'” To be fair, even then-CEO of Twitter, Dick Costolo, was impressed by it. “@SophiaBush hey, @ev told me about the air hashtag,” he tweeted in 2012. “I’m spreading it around the Twitter office. Love it. Big hit here.” No big deal.
