Placement.

A friend of mine has a tattoo similar to this except it's on the other side of her arm. This way when she wants to show people her tattoo she doesn't have to lift her arm to reveal the tattoo, a possible stench and (for some reason) a devious look that screams International Male catalog model. Kind of takes away from the meaning, I guess it's some sort of symbol from Norway that means protection and invisibility. Please protect me from him by making him invisible.
