As an extension of the "Don't Grab the Body Part", don't move the clothing, or in my case, hair, to see the rest.
Also, this has only happened once, but it really bothered me!
I have the Greek word ἀρετή on the back of my neck. It essentially translates to "Being the best you can be", but it's much easier to explain as "Virtue".
I went to a Halloween party where I did a bit of drinking and wore a fairly skimpy outfit. A guest there asked about my tattoo, I told him it meant "Virtue", and he basically said that I was a giant hypocrite for having the word virtue on my body and then dressing like a harlot.
Many people get tattoos with personal meaning that you don't understand. I didn't get the word "Chastity" on my neck, I got "Virtue". To me, "Virtue" doesn't translate to "Not wearing short skirts."
