BJ Penn (Pictured) and Rory MacDonald had engaged in a bitter war of words leading up to their UFC 152 showdown. However, the chatter between the two has cooled since MacDonald was forced to withdraw from the September scrap with a eye gash.

Well, the welterweights were back at it late Monday night. Now that their shootout has been rescheduled for UFC on FOX 5, they wasted no time in rekindling their rivalry.

MacDonald started things off by tweeting the following message and pic.

“200lbs and @bjpenndotcom thinks i care if hes in shape for the fight or not #newgenerationmindset,” MacDonald wrote.

Penn immediately returned fire by spotlighting MacDonald’s bacne.

Here’s how the rest of their conversation went down:

Penn: Great!!! I frekin love knocking out 200 pounders

MacDonald: Do u [mean] knockin back quarter pounders? Who r u kidding, certainly not yourself ?

Penn: Quarter pounders?? Really pimple boy? I won’t even RNC you… afraid of all the pimples on your back. #GROSS

MacDonald: I didnt think it was possible but somehow u made yourself even less of a threat.

The 170-pounders will get to settle their differences inside Key Arena in Seattle, Washington. Although, don’t expect for this to be their last exchange leading up to their December 8th fight.
