Clanker

Clanker was a slang term used to refer to droids that existed since at least the days of the High Republic Era because the joints and metal bodies of droids made noisy "clanking" sounds as they moved. It was commonly associated with and often used by the clone troopers of the Republic Military, who faced off against the battle droids of the Separatist Droid Army during the Clone Wars. During the war, "clanker" was often used as a term for battle droids, particularly the B1-series battle droid. Despite being a cyborg, Supreme Commander General Grievous was nicknamed the "head clanker" by clones. Nonetheless, the term was used to denote other droids as well. For example, Kthoo-Ra addressed a damaged service droid as "dumb clanker."

The motifs featured on the monitor of Lucky Shot, a slot machine found in Cid's Parlor, included an array of B1 battle droid heads. Fittingly enough, "clanker bonus" was written in Aurebesh above it.
