Michael Vick's younger, extremely annoying, brother Marcus Vick has started a twitter beef with Buffalo Bills running back, LeSean McCoy, who he claims gave his baby mama herpes.

Marcus has been sending out tweets this week about someone he knows who has been spreading herpes around, and today he finally flat out named McCoy, which will surely warrant a response at some point. 

Vick's ex who he is alluding to is Delicia Cordon- she has also taken to twitter to vehemently deny his claims while also throwing his brother Mike's name into the mess.

Her tweets have since been deleted but you can see the screenshots here:

Check out a series of Marcus' tweets below, followed by some internet reactions to his latest twitter rant.
