Get the ride the Bakerloo Line mug.
When you do the equivalent of titty-fucking a girls ass cheeks or dudes if thats your bag.

I got the idea from a series of Bahama vacation ads on the New York Metro winter of '07. One has this woman being fake quoted as saying "before my bahamvention, people could take donkey rides down my frown lines", which sounds pretty kinky to me. So I got to thinking, what exactly would that sexual act be? Ive tried it to make it official, so spread the word and happy donkey riding everyone.
Oh damn, that chicks got plump 'ol behind. Id love to do some donkey riding down a frown line of hers.
