Baker Mayfield and Co. clearly had JuJu on their minds after taking care of business Sunday night ... trolling the TikTok-loving star with a taste of his own medicine.
Kareem Hunt, Jarvis Landry and more led the Browns' insane locker room celly following their 48-37 win over Pittsburgh ... blaring Pop Hunna and Lil Uzi Vert's "Adderall (Corvette Corvette)" and having some choice words for the receiver.
Remember, JuJu was infamous for his pregame ritual -- which included dancing to the same song while standing on opposing team logos prior to kickoff.
Landry mocked JuJu with some moves of his own ... while several Browns players recited the receiver's bulletin board material.
"The Browns gon' be the Browns!!!" Hunt said on IG Live ... with guard Wyatt Teller adding, "Same old Browns, huh?!"
It's a huge moment for the Browns ... who now have to prepare for the defending champion Kansas City Chiefs next week.
