UFC welterweight Jake Ellenberger has recently gone after his UFC on Fox 8 opponent Rory MacDonald via Twitter.  He has referred to MacDonald as “McDummy,” called the Canadian an idiot, and asked his followers, “Which round is Rory getting melted?” MacDonald fired back questioning Ellenberger’s chin and promising to send Ellenberger back to reality. Ellenberger was asked about his Twitter attacks during a media conference call on Tuesday promoting the July 27 UFC on Fox 8 event. “I haven’t said anything that wasn’t true and my message to Rory is pretty clear: start tasting some flavors of baby food and find one you like and stock up because this isn’t a Tears for Fears lookalike contest,” he said.  “All I said is for him to prepare for some horizontal television time, and I meant it.” Confident, Ellenberger is excited for the match-up and doesn’t think the 23-year-old MacDonald has ever faced anyone like him. “I’m going out there to perform and to win.  Rory doesn’t have a choice where this fight goes.  This fight goes where I want it to go, and I’ve shown that in past fights,” said Ellenberger.  “He has shown that he has potential, but he has not faced anybody like me.  I’m stoked to get in there.” On Twitter, Ellenberger stated that it was a bad idea for MacDonald to accept a fight with him and he continued with that stance on the  conference call. “I’m an evidence-based abuser,” he said.  “I didn’t make him make the stupid decision to fight me.  I’m just going to make him look stupid when I destroy him.” Be sure to  Like MMAWeekly.com on Facebook  and  Follow @MMAWeeklycom on Twitter .
