Zac Efron's New Hand Tattoo -- What's It Mean?

"New Year's Eve" star Zac Efron got some new ink!
The 24-year-old actor showed off his fresh hand tattoo yesterday during a press conference for his new movie in Tokyo -- flashing the word "YOLO" the side of his palm.
So ... what's it mean?
Turns out it's an acronym for You Only Live Once.
This isn't Zac's first tattoo though, he's also got a giant feather on his inner arm that he showed off earlier this year during a shirtless photo shoot on the beach. Check those pics out again below:

Zac Efron's tattoo doesn't look nice. He could be on another part of his body

Why would he want to deface such a beautiful body? Shame, Shame.

Well, his latest movie bombed. He should stick with High School Musical

In Celtic Hebrew "yolo" mean "guess what I use THIS hand for!"
