Parents have the right to choose whatever name they wish for their children, but most of us will have the common sense not to name our kids something that could negatively impact them in life.
And while naming conventions continue to evolve and children with increasingly unusual monikers become more common, there are some words that just don't work as baby names.
One woman on Reddit has found herself battling against her sister when it comes to the name she's chosen for her baby boy, as she believes it will lead to her future nephew being "mocked", even if his mum thinks it's "cool and unique".

The name? Paradox.
Sharing her story anonymously, the woman explained: "My sister is eight months pregnant, she told me a few weeks ago that she thinks she wants to name her baby boy Paradox, purely because it sounds cool and it's unique.
"I honest to god thought she was joking."
The woman has tried texting her sister with alternative names she could pick instead but has left her sibling so angry that she's now been blocked on social media - with her sister "refusing to acknowledge her existence".
She added: "Ever since then I've been texting her a bunch of names, hoping that she'll pick a different one.
"Yesterday she got super annoyed and asked me why I kept suggesting names when she already picked the name, so I had to be honest and I told her that Paradox is not a real name, and she and her son are gonna be mocked. I've genuinely been stressing out about it because I know she is making a massive mistake.
"Now she has blocked me on everything and is refusing to acknowledge my existence."
The aunt-to-be admitted she understands her sister can name her baby whatever she wants, but at the same time thinks there's "a line" when it comes to appropriate monikers.
She said: "I asked my mum what she thought and she agrees that the name is 'a little out there' but it's my sister's choice at the end of the day. I agree that people have the right to name their kid whatever they want but surely there is a line."
Commenters on the Reddit post were split on the topic, as while some said she was right to point out how ridiculous she believes the name is, others insisted she should "drop it" and let her sister make the final decision.
One person said: "You’re not the a**hole for letting your sister know your opinion, but you’ve done all you can do at this point. Drop it and let your sister make up her own mind."
While another added: "Just because she thinks it makes a cute baby name does not mean it makes a good adult name. That baby is only a baby for a very short time! No one in the adult world is going to take that guy seriously."
"Even though you are correct and that is a ridiculous thing to call a baby, very few people on this planet want their family's negative feedback on their baby's name", a third stated.
