The Mobile Dick Sucking Unit or 'M.D.S.U' for short is a contraption devised to enable players to get head while walking along, thus enabling them to continue day to day life, while pimping it up.
It's basically a tray on wheels.
Guy 1: 'Did you see that badman walking along and getting sucked off by that slammin' hottie at the same time?'

Guy 2: 'Yeah mate, that's Kessah using his Mobile Dick Sucking Unit / M.D.S.U'
