"Burrowhead" is dead in the Bengals' locker room ... at least, that's according to Cincinnati star kicker Evan McPherson, who tells TMZ Sports the jab was a one-time thing that the team is definitely not using as a rallying cry heading into the big game against the Chiefs.
Cincy defensive back Mike Hilton coined the term following the Bengals' playoff victory over the Bills last weekend ... using it as a way to describe Joe Burrow's recent dominance over Patrick Mahomes, K.C. and Arrowhead Stadium.
