What is Guillotine?
1.
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"
