Chael Sonnen likes being the smartest guy in the room. But every once in a while, somebody manages to throw something at him that he genuinely doesn't know. This time, it's an acronym: IGBMN. Chael admits he's never heard it before, has never heard anybody say the acronym out loud, and immediately decides that probably means it's going to be something bad. So what does IGBMN mean? Chael has to do something we're not used to seeing, look it up. It's a short, funny moment that shows a different side of Chael Sonnen as he gets completely stumped by a phrase he's never encountered before. Sometimes even the smartest guy in the room needs to check the internet. #ChaelSonnen #UFC #MMA #MMAComedy #Chael #UFCNews #CombatSports #MMAFans
