It's Zayn Malik's tattoo!

The One Direction member has quite the vast and varied collection of ink and the meaning behind this one is rather...abstract. He explained in a radio interview, "Basically, it's a secret society of club Zappers. Me and Louis are Captain Zappers, the other boys - they're a part of club Zap but they're not Captains, they're just on the board of Directors." That's... interesting?

We might have been a little more into the meaning if it had stood for 'Zayn and Perrie.' Silly meaning or not, it's a pretty sweet tattoo!
