And by that we mean his head made the short trip straight into another guy's head!
Shia was spotted (and captured on video) getting ready to throw down with a man in a London pub on Thursday night.
It appeared Shia was having a family night with GF Mia Goth and her mother at the Hobgoblin in South London when another bar patron had some words that piqued Shia's Fury.
Shia demanded the man repeat his words, but we guess he wasn't in the mood to throw down, because he kept it zipped.
Eventually, Shia's lady dragged him away without further incident, and thank goodness! We're all for defending your mom-in-almost-law's honor, but violence like this is not the answer!
