Courtesy Tap 

When a woman gives you oral sex and you are about to climax. Just before you ejaculate you give the woman a tap on the shoulder that tells her to stop so you can finish into a cup or the toilet bowl. Usually done if the woman does not enjoy the taste or swallowing ejaculate.

"My man is so nice. I was bobbing for apples and he gave me a courtesy tap before he jizzed in my face."
