The tattoos we have are replicas of the Tui beer logo. Trashy? Depends how you look at it. The tattoos include no text, just the image of a Tui bird, mine on the inside of my arm and hers on her hip. Our flatmate at the time got one as well, although we have since lost touch with him. Ours remain as tributes to our bond, which began in earnest the day she moved in.
The Tui tattoos do represent the beer brand, but not in the way you may think. They represent the 4 years we spent in that house - me the entire time, my sister on and off, but always somewhere nearby. Those 4 years saw me go from 20 to 24 and my sister from 17 to 21 - particularly important years as far as years go.
