Many men want an upper arm tattoo so it will be covered most of the time for work. Many jobs still do not want employees to have tattoos exposed. An upper arm tattoo is also a good place for someone to get a tattoo who has never gotten one before. It does not seem to hurt as bad there.
Many people love the Christmas season so much that they get tattoos inspired by the holiday. I have seen everything from Santa, snow, The Grinch and more. Men and woman have gotten these awesome tattoos. Just try and be original. Get a good artist to do it.
