One of the most viral tweets in mixed martial arts history is not what you think.
No, Bjorn Rebney did not run south of the border following his departure from Bellator MMA in 2014. Nothing of the sort. Still, his most recent tweet for more than two years — simply the exclamation "MEXICO!!" — became a running gag on MMA Twitter. It's been retweeted more than 400 times since June 29, 2014.

For the first time, Rebney explained the origin of the tweet to Ariel Helwani on a recent edition of The MMA Hour.
