That guy is a reg. Saw him saying "ty fish" to a whale after he busted him. Slowrolled him hard with AA vs. his AK button vs. bb as soon as I got the chance.
Sorry to disappoint you guys but that's NOT him in his avatar. The pic is a well-known viral image and a meme of a typical gopnik (a small-time street thug). Can be found here (along with bunch of his buddies): http://trinixy.ru/page,1,3,2055-gopota2.html
Your quintessential reg-fish; that rare creature that not only puts in a lot of volume across multiple tables but does it all while simultaneously playing as badly as is possible. A first class selfie though.
