Went to a party NYE and a couple friends had been doing quite a bit of drinking. One of them thought it would be funny to get some lipstick tatoo's done by her friends. The next morning she was still covered in lipstick. She said 'when they say 12 hour lipstick, they really mean it. I tried washing this crap off an it's not going anywhere.' Might be something to the theory that lipstick is hard to get off.
