Personal Stamp 

The act of jerking off in one's own hand while their girlfriend sleeps, then being careful not to wake her, rolling over and stright-arming her, plastering her right in the forhead as if she were a peice of airmail. The most common response is one of complete shock and awe, or just: "You've got to be fucking kidding me.

My girlfriend was being a real treat the other night, so I waited for her to fall asleep then gave her my personal stamp.
