The news left netizens in a frenzy, and it was once again the unique name of the newborn that triggered memes and jokes online.
The couple, who has a son named X Æ A-12, X for short, have named their daughter Exa Dark Sideræl, and is fondly called Y.
“A girl named Odysseus is my dream.” However, that didn’t happen and the couple went for yet another unique name for their second child.
Sideræl which refers to “the true time of the universe” is also a shoutout to Grimes’ favourite Lord of the Rings character, Galadriel, the magazine added.
While most wondered why Musk and Grimes are keen on such unusual names, it also led to many memes and jokes online involving mathematical equations.
