Never tattoo your boyfriend's/girlfriend's name on your body. Partners come and go but tattoos remain, unless you can afford painful laser surgery. Even the Tattoo Queen herself, Angelina Jolie, learnt this the hard way, erasing her ex-husband Billy Bob's name from her arm after their divorce. Don't tattoo your own name on yourself either. Unless you're in the habit of forgetting it....Never tattoo curse words on your body. You'd think this was a given, but alas, no. Remember, you won't be a rebellious 20-something forever; at some point you might care what other people think of you.
