A bond, sometimes romantic, that forms between two members of the opposite sex who smoke weed together frequently. Named after an apocryphal story included in some editions of Arabian Nights in which Mustapha, a hashish merchant, has a tryst one of his customers, who is the wife of a local sheep herder. Mustapha and this woman smoke together a bunch of times and then start Kissing On The Lips. When her husband finds out he gets hella pissed and kills Mustapha as a sheep herder would. It Is Pretty Brutal.
Dogg, this ladybitch and I smoked out of her bong ten times this past weekend and we got this crazy Mustapha's Rope thing going on.
