First you must go into McDonalds and order a double big mac. Then you go into the bathroom with your burger and masturbate until you are about to cum. Then you put you dick in the hamburger and walk out into the dinning area with your hamburger on a tray at dick level. Finally you find a person sitting down and ask if they want mayo. Regardless of their answer you pull the hamburger and cum all over their face.
