Giants defensive end Osi Umenyiora only joined Twitter on May 3, but he seems to have pretty quickly grasped one of its primary uses: taking long-distance pot shots at rivals and inciting a media furor.
This morning Umenyiora posted this on the social network: "Happy Mothers Day Lesean Mccoy! Enjoy your special day!!"
When a follower wrote to Umenyiora after the post, he responded, "hahaha u know the beef is never over. Never."
Last year McCoy wrote on Twitter that Umenyiora was "overrated n soft." The Giant then told the Newark Star-Ledger that "he's a girl, man. Who does stuff like that?"
He added, "If he has more of these things to say, he can say 'em to my face. Don't be no Twitter gangster man."
Apparently that rule no longer applies. And it's only May -- the Giants and Eagles play in Philly Sept. 30.
