Bukake
I term brought to mainstream America in recent years by popular radio show host Howard Stern.  

The origins of the word have little to do with the current American meaning.  In Japanese, bukake means splash or spill... The American definition is much different, in English bukake describes 1 or more men jerking off on a whores face until it drips everywhere.  

In western culture bukake is a very enjoyable part of a relationship for both men and women.  It is also very common for a women to have her entire face covered in cum or jizz.  
John and his friends learned about bukake from Howard Stern so now they bukake on every women in sight.
