'Bubba' Wallace, Brian Scott spat gets ugly, spills over to Twitter

Drivers Darrell Wallace Jr. and Brian Scott had a passionate disagreement after Saturday night's XFNITY Series race at Kentucky Speedway, where Ryan Blaney took the victory.

Angry about contact with Wallace that loosened his right-rear wheel, Scott twice approached the Roush Fenway Racing driver on pit road after the race to express his displeasure.

From there, the two engaged in a profanity-laced shouting match -- the contents of which were apparently REALLY personal.

Still steaming from their encounter, the two combatants carried their war of words over to Twitter.
