Billionaire Elon Musk and Canadian singer Grimes have named their baby X Æ A-12. Apparently, the name is pronounced “X ash A-12″.

However, Musk may not be able to legally name is child ” X Æ A-12″. In the state of California, only the 26 letters of the English alphabet are allowed to be used on birth certificates. Therefore, Musk would not be able to use the symbol Æ or the number 12 in his name.

While the name may seem like a random jumble of letters and numbers, the name does in fact have a meaning. Grimes even tweeted the meaning behind the strange name to all of her fans.

“I don’t understand [the name]”, said Junior Jake Dillon. “I don’t know why anyone would want to name their kid that.”

Junior Yulieanna Sim also said, “I feel like rich people always name their kids something stupid, but this is outrageous.”
