Modafferi, a contestant on the upcoming season of The Ultimate Fighter 18, opened a can of worms by taking to Twitter to find out what UFC supporters had to say about the issue, but perhaps it will bring some closure to a debate that has heated up over time.
The jury is still out, but several notable fighters and other active voices in the women's MMA community responded with suggestions that WMMA would be best referred to as the "Women's Division."
"Womens MMA for everything outside UFC and Womens Division in the UFC," WMMA consultant and matchmaker Sam Wilson said in response to Modafferi's post.
Legendary WMMA fighter Tara LaRosa seemed to agree with Wilson.
"Women's division," LaRosa posted as her suggestion.
Several media members also weighed in on the matter, and the responses were varied.
"I've been working on using 'women's divisions' as of late, if I don't use it I use WMMA, never women's MMA," said Marq Piocos of Wombat Sports, a leading source of WMMA news.
Kristin Usry of WMMA Roundup added "I like referring to the women's division of MMA as WMMA."
Some have argued that WMMA is a perfectly fitting term for women's mixed martial arts since WNBA is used for the Women's National Basketball Association.
However, that argument doesn't make sense since MMA is a sport, while the WNBA is a league.
After much back-and-forth discussion, the only thing clear is that this debate has no end in sight.
Is it better to refer to WMMA as 'The Women's Division' of mixed martial arts? Let us know in the comments or tweet the author, @ericholden.
