The group, which features UFC bantamweight champ Ronda Rousey, TUF 18 contestant Shayna Baszler, top-ranked 145-pound amateur Marina Shafir and UFC bantamweight contender Jessamyn Duke, is a throwback to pro wrestling's glory days of the late-80s', when The Four Horsemen reigned supreme.
The original Four Horsemen included Ric Flair, Arn and Ole Anderson, along with Tully Blanchard, so the Four Horsewomen name is a bit of a tribute to some of the pioneers of pro wrestling.
Some hardcore MMA fans don't want pro wrestling to have anything to do with their beloved sport, but there's no denying that there's a great deal of crossover between fan bases.
Wrestling is entertainment mixed with athleticism and fighting, while MMA is athleticism laced with an entertainment factor.
Wrestling is also one of the key bases for MMA, and one of the UFC's most popular stars of all-time -- Brock Lesnar -- came from a background in pro wrestling.
Late last year, perennial bantamweight contender Miesha Tate said she thinks Rousey appeals mostly to pro wrestling fans.
"She runs her mouth," Tate said of Rousey. "She's very loud, very boisterous, very opinionated. Love her or hate her, you take notice of her. I think that's the biggest thing. She's different than most of the girls who fight in MMA.
"A lot of fans out there have the WWE mentality. Those are the fans that fell hook line and sinker and loved her. She was that controversial one, that s**t talker, she started drama."
In pro wrestling, fans get sucked into scripted story-lines that are based on drama between two rivals.
Since MMA isn't scripted, the athletes are usually respectful towards each other and the average fight lacks real-life "beef" between combatants.
Rousey changed all that with her actions toward Tate, and she fully admits she enjoys playing the role of the villain.
As for the rest of The Four Horsewomen, Baszler is well-known for her love of old school pro wrestling, and Shafir's charismatic personality helps round out the group.
Additionally, it shouldn't come as much of a surprise to see Duke in the group, since she was part of Team Rousey during TUF 18.
Very rarely do groups of high-level superstars thrown together work as a tag team, but The Four Horsewomen are clearly here to stay.
