Even after the Kansas City Chiefs had dispatched the Buffalo Bills, Brittany Mahomes couldn’t resist calling out Bills Mafia for a “disgusting” act.

Shortly after the hosts knocked off Buffalo on Sunday in an AFC championship thriller, the wife of star quarterback Patrick Mahomes posted a pointed message to Bills Mafia on her Instagram Stories.

Brittany called out the Buffalo faithful for the “absolutely disgusting” behaviour that was on display when the two teams met in Week 11 of the regular season.

Brittany posted a snap of a Kermit the Frog puppet decked out in Patrick’s jersey and a wig being hung from a pole with a noose around its neck.

“Do we remember this Buffalo? Absolutely disgusting … So as you go home tonight, I pray we become better people,” Brittany wrote.

The star quarterback’s voice has often drawn comparisons to Kermit’s.

The snap, which was taken outside Highmark Stadium in Orchard Park, N.Y., went viral and sparked outrage on social media at the time with many condemning Buffalo supporters for crossing a line.

The Week 11 game marked one of the Chiefs’ two losses on the season with the second coming in the final game of the slate in which K.C. rested its star players.
