When a guy lays his cock and balls out on someone's face.
The balls need to be over the victim's eyes, and the dick needs to be laying over the nose and the mouth (if you can reach that far.)

The name comes from the fact that this will look like the victim is wearing a medieval mask/helmet, like King Arthur wore.
Oh man, when Daylon was passed out drunk, I gave him a King Arthur and took pictures. I left one in his pocket for him to find when he woke up.

He's a King, therefore he's a ruler. And a ruler is 12 inches. Thus the name King Arthur.
Don't let King Arthur unsheathed his sword or he'll cum-a-lot.
