star wars - Why does Greedo say "Maclunkey" in the Mos Eisley Cantina?

In the Disney+ edit of Star Wars (1977), yet another change has been made to the "Han Shot First" scene in the Mos Eisley Cantina.

Greedo now yells "Maclunkey!" before shooting simultaneously. [Video Clip]

This is the only non-subtitled word of Greedo's language.

To the ears of a Galactic Basic speaker, the line sounds like:

• "Maclunkey"



• "McClunky"


• "McKlunky"

In-universe, why does Greedo say "Maclunkey" before shooting at Han Solo?

Behind the scenes, why was this new line of dialog added to the already controversial scene?
