Jake Paul absolutely eviscerated Tank Davis after their fight was scrapped just days before it was slated to go down ... calling his former opponent an "actual walking human piece of garbage."
El Gallo unloaded the social media blows on Davis minutes after it was announced Netflix and Most Valuable Promotions would no longer move forward with the Nov. 14 bout ... saying top to bottom -- the guy was a "nightmare" to work with.
"The unprofessionalism, the bizarre requests, the showing up hours late to shoots," Paul said on X.
