Lady Shay needed to pass a message to this guy and she did it with her feet. She had made sure that she filed her feet and she used the dust to humiliate as well as degrade the guy. He was shocked at what she did to him and he tried to reason with her to stop it but she did not listen to him and instead made fun of him.
Lady Shay had muddy and stinky shoes and she used them to scare this loser. She knew that this loser had never seen her in action and she knew he did not know what to expect from her. She got the loser to lick her feet as well as to lick her muddy sneakers and stinky socks. He was shaken and scared of her and he did what she asked.
