Baker Mayfield is teeing off on the Big 12 Conference for penalizing players who mock Texas' famous "Hook 'em Horns" hand gesture ... saying the world is getting way too sensitive.
Conference honchos announced last month that any player who directs a "Horns Down" gesture towards Texas' team or student section will be hit with an unsportsmanlike conduct penalty.
Bake -- who was a big advocate of the hand sign during his time at Oklahoma -- thinks it's a bunch of BS ... sounding off on the decision on Barstool Sports' "Pardon My Take" on Friday.
