The act of shanking someone through the temple into the brain while he/she blows you, causing him/her to involuntarily bite down on the penis with maximum force, as they die. Often suggested as a test for the virility of the shank-er (as a sufficiently turgid member should withstand the maximum force exerted by a jawing).
This bitch started throwing up while rimming me, so I gave her the ol' Arabian Guillotine. In retrospect, I may have acted rashly. Such is life.
"Give her the ol' arabian guillotine!"
