Ronda Rousey is a MMA fighter that had a former hook up reach out to her on Instagram. Well, she didn't harbor very warm feelings for the old flame as she told him to "F#$% off." The dude tried to get back in contact with her after not calling her back. Apparently she didn't like the fact he waited till she got famous before trying to get back in contact with her.
