Picture this: You're looking through family vacation photos of a recent trip to Hawaii pondering how amazing you look in your bikini, when suddenly you notice something on your lower back. Is it a bug? A weird tan-line? Nope, it's the "tramp stamp" you got on a whim back in college, and it's officially come back to haunt you. Getting a tattoo always seems like a fabulous idea at the time (who doesn't need "mom" etched in permanent ink on their bicep, right?), but irresponsible ink is a one-way ticket to Regretsville, population you.
