Not bad luck, exactly, but imagine poor Johnny Depp. “Winona Forever”, he had tatted, but alas! Such was not to be. He had to go and get it changed when they broke up. It now says “Wino Forever”. Seeing that he lives in France, that’s probably an accurate assessment of his current situation.
Lesson: If you’re going to get a tat of someone’s name, make sure it’s easily chageable at a later date to a beverage or foodstuff.
