Mark Zuckerberg's shirt says 'All Zuck or All Nothing' in Latin

• Mark Zuckerberg wore a custom t-shirt with the Latin phrase "AUT ZUCK, AUT NIHIL" at Meta Connect.
• It's a play on "Aut Caesar, aut nihil," which means "Either a Caesar or nothing. (Or: "All or nothing.")

At the Meta Connect developers' event, CEO Mark Zuckerberg wore a black boxy custom t-shirt with the words "AUT ZUCK AUT NIHIL."

In Latin, this translates to "All Zuck, or all nothing" — a play on the famous phrase "Aut Caesar, aut nihil."

This isn't the first time we've seen Zuck wear this kind of shirt.

At his 40th birthday party earlier this year, he wore a black shirt with the phrase "Carthago delenda est," which means "Carthage must be destroyed." (More on the meaning of that phrase from my colleague.)

Zuckerberg has been experimenting with more flashy fashion in the last year or so (and you sickos keep encouraging him). It's a notable departure from this former hoodie and plain grey tee uniform.

We know that Mark Zuckerberg is a fan of Roman history. He named several of his children after Roman emperors and has talked about how he's fascinated with Roman history.
