With one son already and another on the way, she says that she “chickened out of” calling her firstborn the name due to negative reaction.

The old French name means “pertaining to the wolf”, according to Nameberry. 

The mum, who chose to remain anonymous, claims to love the “edgy and unique” moniker based on this, as the meaning creates an air of masculinity. 

The name in question is Lupin. 

Yes, that’s how we know Remus Lupin, a Hogwarts professor in the Harry Potter franchise who turns into an ugly werewolf. 

It’s also the name for a tall-growing flower. 

“My husband and I have loved this name since conceiving our first son,” the pregnant mum wrote on Mumsnet. 

“Lupin is edgy and unique; it also has the more masculine meaning of ‘pertaining to the wolf’. 

“It could be shortened to Lu or Louie. 

“We chickened out of using it last time because we got a few negative comments and thought it was a bit too unusual. 

“But on the other hand it could be paired with a very ordinary middle name that he could use if he preferred when older.”

Fellow Mumsnet users were quick to question if she was joking, warning: “I’d think you are massive and slightly cringy Harry Potter fans.”

“Absolutely not,” one slammed. “It’s just awful. 

“I can’t believe you are even considering it, especially more than once.”

“You are naming a human being, not a pet,” another said. 

“Please don’t saddle your son with a name like this,” a third pleaded. 

“Can you imagine him as a teenager with a name like Lupin? 

“It’s cruel, and frankly bats**t.”

Others thought Lupin sounded “like an illness”, with some saying it sounds too similar to the autoimmune disease lupus. 

Similarly, there were a number of warnings that he may be bullied at school for the moniker and nicknamed “loopy” or “loopy Lupin”.
