I may be over-explaining but it was long ago enough that it probably isn't the common knowledge it once was. That logo was on the back of the UH basketball team jackets. It wasn't an actual fraternity. Phi Slama Jama was a nickname for the early-80's UH team that featured Hakeem Olajuwon & Clyde Drexler. They went to three straight Final Fours & really helped popularize the above-the-rim style that's so common now. Best team ever to not win a title, in my opinion. I believe the logo itself, as well as the jackets, were made by a relative of one of the players ...so not really an official team mark, but perhaps semi-official since the team did use it for sideline gear.
