When you were growing up, chances are you would've had a pillow fight with your mates.
Some people might have grown out of that playful bit of fun, however others decided to turn it into a professional sport.
Introducing the Pillow Fight Championship (PFC), the legitimate sport that sees two people battle inside a ring with a comfy-looking pillow.
It's very similar to the likes of boxing, however you're allowed to use a specialised PFC-branded pillow to absolutely wallop your opponent with.
According to their website, Pillow Fight Championship started 'with an idea to develop a real fighting sport that would appeal to the international family audience by combining the ancient weapon known as a 'pillow' with experienced MMA competitors & boxers an strict rules'.
There are three, two-minute rounds in each fight.
The PFC said they have 'quickly evolved into a very popular sport-based showcase complete with all the strength, stamina and strategic skills of the other more brutal combat sports but with a massive amount of fun'.
They pride themselves on having 'all the thrill of a hand-to-hand combat fight without any blood and a lot more action'.
A PFC battle was held over the weekend in Florida and the pay-per-view event and saw 16 men and eight women compete for their chance at a title belt and a cash prize of $5,000.
Brazil's Istela Nunes won in the women's division and American Hauley Tillman took our the men's. They've been officially crowned as the first-ever PFC champions.
The competition has attracted some UFC stars, including Conor McGregor's first opponent, Marcus Brimage, and Markus Perez.
But the new style of fighting proved that there can still be some non-pillow-related argy bargy.
Perez was in the middle of battling MMA fighter and fitness coach Reggie Newsome when the latter lost his pillow.
Despite this, Perez continued to attack him and that sparked a heated showdown before a referee stepped in to calm emotions.
PFC boss Steve Williams hopes the sport will take off soon.
"The fighters don't like to get hurt, and there's a lot of people who don't want to see the blood. They want to see good competition, they just don't want to see the violence," he said.
There will likely be loads more PFC tournaments held over the coming months and hopefully we could see some absolutely brutal blows.
