When you fill a bathtub with water almost to the top and a couple engages in intercourse doggy style while the receiving partner's head is placed underwater. The pounding partner repeatedly dunks their head under water and says "Who's the Master Leroy!", a situation reenacting a scene depicted in Berry Gordy's the Last Dragon where Shonuff does the same thing to Bruce Leroy in an act of dominance. Proceeding until someone "gets the glow",i.e. Reaches climax.
