A sex act involving meticulous preparation whereby a male (or female with penis) shaves his testicles, gooch and head and proceeds to store the shaven hair. Step two requires minor culinary skills in that a couple of Mars Bars must be heated in a pan and brought to highly viscous (thick), yet fluid, syrup. The newly created concoction (after cooling to a lukewarm temperature) is then carefully lathered onto the perpetrator’s earlier prepared erected penis and testicles. All the shaven hair is generously applied to the chocolate-coated trouser snake until it is completely covered to create an ‘ewok-type’ appeal. The final, and crucial, step is to coax a female to initiate the art of felatio on you and, in a jack-in-the-box-style maneuver, reveal your Middle Eastern Mars Bar.

*NB: It should be noted the Mars Bar syrup possesses both practical and aesthetic purposes:
Practical – to allow the hair to stick;
Aesthetic – to act as a dark background to the hair
