The act of giving a female a mustache ride when the following criteria are met:
-The female is under the age of 18 (or whatever your legal age of adulthood is pending on country/state; does not apply in Mexico.)
-The ride-giver must be in possession of a luxurious, well groomed mustache.
-The ride-giver must be at least twice the age of the rider.
Mort loves to hit up the Elementary School across the street after work; he is such a mustachatory rapist.
Merwin was totally busted again for mustachatory rape, that's the third case on his record! That means he is never allowed to be in possession of a mustache again!
