The masta of cawk. Usually one with a high proficiency with his own cawk or others. A man who has the ability to control all the cawk in the land, and all other cawks bow down to his sexual prowess.
Damn dude, Greg is such a cawk masta. I feel like I have mangina whenever he comes around. His mastery of the cawk makes mine shrivel away and hide!
Betsy loves to be rode by a cawk masta.
