Don't worry, there's a logical(?) explanation.
Elon Musk and his partner Grimes welcomed a baby boy yesterday, and they've decided to give the newborn a unique name.
In a series of tweets, Musk confirmed the birth of the boy and that mother Grimes was doing well, while also sharing a photo of the baby complete with face tattoos thanks to an Instagram filter.
As for the baby's name... it's X Æ A-12.
While people may have initially thought it was a joke, Grimes explained the meaning of the name with a tweet of her own.
So that's the meaning of the name. As for the pronunciation, good luck with that one!
