When you are fucking a girls wet, tight, warm, steamy, virgin pussy and you have to pull out. Right before you cum, you get her to look at you and then you laugh in a very cinical way shooting your hot, salty load all over her face.
The Joker Special is when you are railing the stripper you just brought back to your hotel room doggy style. It is hot and sweaty. You pull out, laugh in the moment of the gesture and she looks at you with a look of confusion. Then, you blow your load while laughing in the hoes face.
