Sexual favor, a handjob where a woman masturbates the man with one hand while inserting the thumb into the rectum. Right before he ejaculates she pops her thumb out in the same manner one uses their thumb to make a loud popping sound with their cheek.

a lucky anderson is where a girl beats off a guy and shoves her thumb in his ass, then when he is coming she yanks out her thumb in the same way you use your thumb to make a popping sound with your thumb in your cheek.
