The latest in our ongoing series of Tattoos You Will Regret comes courtesy of singer/rapper T-Pain, who took Facebook’s like button beyond the web and onto his arm.

It's not you we don't like...

For one thing, where’s the apostrophe in “don’t”? Guess T-pain’s tattoo artist doesn’t have to like punctuation. Back to the larger point: in an age where technology changes constantly, do you really want a lifelong tattoo based on something that may not be recognizable 10 years from now? Honestly, we never though we’d see anything that would make a brand tattoo look smart, but in this case it may be the lesser of two meaningless tattoo evils.

Just think, what if you’d gotten a Geocities tattoo? Or one for Friendster? Or a MySpace tattoo? Hah, no one would… oh, wait.

A mere few years later, and this guy’s stomach is obsolete. We know Facebook is aggressive in defending its brand, and while we don’t think it’s fair in every case, we wouldn’t mind seeing them send a do not tattoo notice around for cases like these.

To be fair, this isn’t totally new. Jason Preston, the one time boyfriend of designer Marc Jacobs has his paramour’s brand name tattooed on his forearm. While the ink lasted longer than the relationship, at the very least it’s an inking decision lots of other people have made and come to regret.

Unfortunately, it seems a different kind of brand tattoo (that has nothing to do with love – not the normal kind, anyway) is taking off, for people who’ve decided that temporary brand tattoos aren’t cool… REAL brand tattoos are cool. Racked introduces us to the Louis Vuitton tattoo, and the Gucci face tattoo.

Call us old fashioned, but what happened to tattoos with names of family members or loved ones? While there may be something to be said for brands creating the kind of loyalty that would make someone want to permanently associate themselves, we can’t help but hope this falls under trademark infringement since it definitely doesn’t fall under good taste.
