Is that a reference to drek, or Kn'thrak and harakh? Because drek is just idiomatic slang, and the other two are references to a part of Nexus's history that the Nexan people try to ignore or pretend didn't happen, like Americans with slavery, Brits with colonialism, and Canadians with Celine Dion.
I guess harakh is kind of sweary, but Kn'thrak just means the end of all things.
