Many parents have unique reasons for choosing the names of their babies: Whether they named them over a beloved family member or friend, movie character, or perhaps they just trawled through a baby book and found one that caught their fancy.
But one woman's story of how she got her name is definitely one of the more unique - and horrifying - ones we've heard.
On her TikTok account 'Keeping it Kristina', Kristina revealed she was named after the woman her father was having an affair with when she was born, something her mother was completely unaware of.
In the video, she explained: "So I feel like most people who are named after somebody have like a cute story behind it or they're named after somebody really special... that is not the case for me".
"I was my parent's first child and when I was born my parents had an agreement that if I was a boy my mum was going to get to name me after my grandfather, and if I was a girl my dad was going to get to name me."
Kristina said she was born via a c-section which meant her mum was "super drugged up" afterwards - so her dad took it upon himself to fill out the birth papers, naming his new daughter Kristina.
"My mum came too, I guess she didn't really hate the name so she just kind of went with it and you know, everything was fine for a few months," she went on.
"Until my mum found out my dad was cheating on her and guess what the woman's name was - Kristina.
"[It was] so if he messed up and used the wrong name, he could say he was talking about me."
"I just hope I make my namesake proud," she captioned the video.
The bizarre story has racked up over 70,000 likes and encouraged other TikTok users to comment with their own bizarre naming stories.
"My dad heard a story on the radio about a girl named Lenae who was murdered," one girl named Lenae wrote
"My dad named me after a girl he had a crush on in middle school, when my mum found out she stabbed him with a fork," revealed another.
"My cousin is named after his dad's favourite drug dealer," added a third.
Clearly there was no love lost between Kristina and her dad. In a later comment, she added that her father left when she was three years old, and never had contact with her or her sisters until they were adults.
"He went on to have more kids, he also abandoned," she added.
