Dewey wrote the game has been growing in exposure since April, following a "very alarmist (and unintentionally funny)" news report in the Dominican Republic, but buzz seems to have shifted with one Instagram post, when a Georgia girl posted a video Sunday of the #CharlieCharlieChallenge.
"As of this writing, #CharlieCharlieChallenge has been tweeted more than 1.6 million times. More people are Googling 'Charlie Charlie' than virtually any other news event ... That hashtag was, apparently, all the kids needed," Dewey wrote.
The user, __k.luh, appears to be a girl living in Byron, according to her public social media accounts.
"Charlie Charlie" has been picked up around the globe, occasionally breathlessly, following in the tradition of teen-centric #BostonBlizzardChallenge and charity-centric #IceBucketChallenge.
Good news, according to Dewey: The challenge basically amounts to screaming teens, and a healthy dose of self-mockery, as opposed to injured teens in Internet challenges gone wrong.
"Charlie makes a killer case study in virality and how things move in and out of languages and cultures online," she wrote.
