Cris "Cyborg" Justino wants to make plans with Ronda Rousey for the spring.

Justino called out Rousey on Instagram on Saturday, because if you're not making memes of your adversaries online, why bother?

Rousey, who obliterated Bethe Correia in only 34 seconds at UFC 190, is undefeated at 12-0, and is looking for another opponent - rumored to be Miesha Tate, for a third time, in December.

ESPN's Brett Okamoto has more on the second part of Justino's Instagram caption, as Rousey and Cyborg have taken shots at each other with respect to performance-enhancing drugs:

The second point is in reference to Rousey's repeated claims that Justino is on performance-enhancing drugs. Justino, 30, was suspended one year after testing positive for an anabolic steroid in December 2011. In recent years, she has passed multiple random drug tests in Nevada and California.

As the Invicta FC 145-pound champion, Justino is currently subject to drug testing administered by state athletic commissions overseeing her individual bouts. Should she sign to a UFC fight against Rousey, she would be subject to additional testing under the UFC's anti-doping program, which is administered by the United States Anti-Doping Agency.

The program, which went into effect July 1, includes blood and urine tests.

Justino, 14-1, failed a drug test in 2011.

If Rousey and Justino do fight, it'll happen at 135 pounds, according to the UFC. There are doubts that Justino can get down to that weight, and she's been pushing for a 140-pound catchweight fight. Rousey, however, has been adamant about Justino getting down to 135.

"This fight has to happen," Justino recently said. "If the UFC thinks I don't deserve this fight, don't do it for me. Do it for the fans."

Tito Ortiz, meanwhile, claims Justino's already been offered a fight with Rousey, to take place at AT&T Stadium in Arlington, Texas.
