2016 wasn鈥檛 many people鈥檚 year (here鈥檚 a recap of all the famous faces we lost), but it may have just played out worst of all for UFC fighter Ronda Rousey 鈥 at least professionally.

NEW YORK, NY - NOVEMBER 11: UFC Women's Bantamweight Champion Amanda Nunes faces off with Ronda Rousey after UFC 205 Weigh-ins in preparation for their UFC 207 fight that will take place on December 30, 2016 at Madison Square Garden on November 11, 2016 in New York City.

In what was supposed to be her big comeback fight last night (she took more than a year off following her first defeat ever at the hands of Holly Holm last November), the UFC fighter stepped into the ring to face off against Amanda Nunes.

48 seconds later, it was all over for Ronda, as Amanda defeated her with several swift blows to the head, crushing her hopes of regaining her championship title.

While the defeat was shocking, to say the least, it was Amanda鈥檚 response that has Twitter up in arms.

Appearing to have no sympathy for her fallen opponent, she told a commentator post-match, 鈥淚 trained for this girl since my first fight in UFC. I proved to everybody I鈥檓 the best on the planet鈥 Forget about f*cking Ronda Rousey. I鈥檓 the real champion.鈥

And she didn鈥檛 stop there. She made the feud even more public by taking to Twitter to gloat, posting a Photoshopped shot of herself holding the championship belt while pushing Ronda in a stroller.

Justin Bieber (who reportedly once denied Ronda鈥檚 little sister for a photo, spurring some bad blood between the two) was firmly on Team Amanda, composing this charming tweet in her support, but many were left with a bad taste in their mouths over her show of poor sportsmanship.

While Ronda has yet to respond, she did discuss the difficulty she faced after her first defeat prior to the fight with The Mirror. 鈥滻 hear so many of the worst things anyone could even imagine to think to say about me every single day. People are constantly trying to reach me to tell me negative things,鈥 she said. 鈥淧eople want to see people rise, because they want to rise, but they want to see people fall, because they want to feel like they鈥檙e human, like they are,鈥 she said, commenting on our society鈥檚 tendency of raising people up to let them crash down. (She isn鈥檛 wrong: See Taylor Swift and Ken Bone).

We鈥檝e gotta say: Our hearts are breaking for her a bit. While some have questioned her own displays (or lack thereof) of sportsmanship in the past (one Twitter user pointed out that she failed to shake Amanda鈥檚 hand pre-fight, for instance), it can鈥檛 be easy to not only suffer such a crushing blow of a loss, but also be taunted for it thereafter.

Here鈥檚 hoping her 2017 goes better than 2016 did!
