OTB speaks on his relationship with Slim Thug, stating:

“My respect and relationship with Slim Thug is priceless, ever since I’ve been doing music even before I got a buzz he would tap in with me. Ever since day one I could get good game from him and the best thangs on how to move. For me that’s especially priceless for Slim to be in the game that long and have a legacy, that’s something all artist want.”

The popularity of “Dawg Azz” has inspired a viral freestyle challenge that has earned the song over one-million streams. OTB Fastlane on “DawgAzzChallenge”:

“The “Dawg Azz” challenge is really strictly for the fans and the people. Ever since I dropped the song people kept asking me where could they find the instrumental at. It was only right to put some fun into it and let the fans play around so they know they’re a part of it and I always do things for the people so that’s why the prize of giving money away comes in at… They’ve been supportive of me, why not? You got to support the people that support you back. The Dawg Azz Challenge is going dumb and if the people wasn’t supporting it things wouldn’t be going the way they’re going.”
