This a person who has not yet evolved on the genetic level to even pass as a human being. One who is a ballwasher is slime. Crud. The stinking steaming pile of shit on the bottom of your shoe. They would sell out their own mother if it meant they had to ballwash to gain power.
"I am going to bring in cookies to share with the office and I will bake some muffins for the boss"
"Hey Look at that ballwasher going into Darrens office again!!!"
