The act of Ejaculating on/ into a bike without it's consent. Bikerophillia, otherwise known as bike rape, was first discovered in the late 19th century when A Sir. Arthur Rittlewagit fornicated with a wooden, tubular frame of the penny-farthing, later resulting in a series of splinters in his penis.
My goodness. Andrew Sparks is infatuated with his bike, perhaps he's suffering from a common case of bikerophillia!
