Kevin Harvick... for going three-wide in Turn 2 at Darlington to attempt passing the Xfinity race leader... and then performing classless tantrums in the pits and on TV to try placing the blame on Ross Chastain.
Honorable Mention to the Harvick fans claiming three-wide in Turn 2 is a standard move for skilled veterans. Fact: In the Cup race, there were ZERO attempts at three-wide running in Turn 2 shown on the broadcast, either live or replay.
Harvick is the only Harvick fan that I aware of
