The Twitter war between Conor McGregor and Tyron Woodley escalated to a real-life confrontation moments ago ... with Conor screaming at the champ backstage at the UFC weigh-ins ... calling him a "woman."
As we previously reported, McGregor called Woodley a "bitch" on Twitter after an icy interaction at a UFC event Friday morning. Afterward, they trashed each other on social media.
But when they ran into each other at the UFC 205 public weigh-in Friday evening, things got REAL -- with Conor saying, "You're like a woman with that phone ... f**king bitch."
Woodley didn't react ... pissing off Conor even more.
