Pittsburgh Panthers quarterback Kedon Slovis is wasting no time fitting in with his new school ... grabbing a mic and shouting "F*** West Virginia" at a pep rally ahead of their big rivalry game.
21-year-old Slovis was recently named Pitt's starter after transferring from USC this year ... beating out redshirt senior Nick Patti to be Kenny Pickett's successor.
Apparently, the guy already bleeds Blue and Gold ... 'cause when the team hosted an event to get fans pumped up for their "Backyard Brawl" season opener against the Mountaineers, Slovis let everyone know how he felt about the rival team.
