Guillotine 

The act of squatting over one's anus and lowering your scrotum into the open orifice. Your partner then proceeds to clench their anus closed once the testicles are inserted. Thus, simulating the function of the well known, French guillotine. The anus is the "blade" and the semen is the "blood" after said "artificial execution".

"I was feeling a little historical last night, so I made my girlfriend give me the guillotine"

guillotine 

V. or N.

During the course of fellatio, the forceful but willing removal of one's phallic tip, usually running simultaneously with male climax. The action is initiated through an upward thrust to fellater's lower jaw, causing the abrupt closure of the mandible, severing the penile head from the base.

The guillotine is a once in a lifetime experience, i.e. "I'm saving my guillotine for my wedding night...."

Person 2:He must be a Guillotine.
