They clarify with it being "an adaptable expletive" Jul 21, 2017 at 16:38
I suspect that some of the beeps and whistles that R2-D2 directs at C-3P0 might be expletives, as well :-).– LAKOct 5, 2017 at 17:36
One that I have come across in the EU is 'Sithspawn'
I first came across this in the Michael A. Stackpole novel X-Wing: Rogue Squadron. Lieutenant Corran Horn (Rogue 9 of Rogue Squadron) thinks to himself
Great, all I need is some Sithspawn hotshot pilot in that squint"
Note that this is Rebel pilot slang. An 'Eyeball' is a standard TIE fighter, a 'Squint' is a TIE interceptor, a 'dupe' is a TIE bomber & 'Bright' is a TIE Advanced (Darth Vader's personal TIE fighter).

I'm getting a bit tired of cleaning up your answers. There's some quality here, but can you please make at least some effort to learn where capital letters go and how to use the top buttons to add quotes and links– ValorumOct 4, 2017 at 20:15
