The cocaine insults were flying at the UFC 214 media event today -- with Jon Jones saying Daniel Cormier looks like a crackhead.
Cormier shot back -- "I can look like a crackhead, but I've never been a crackhead like you, though."
That was just the beginning ... Cormier accused Jones of being on steroids for most of his UFC career. Jones denied the allegations and flexed his 6-pack.
These guys hate each other -- and will finally get to get violent on Saturday.
