Though I am sure The Void and BKA would like to keep things standardized for the purposes of the forum and I suppose for competitions, I think that's a pretty natural process. My Berlin players say '... Cup, Bird, Lighthouse, Spike (sometimes Stick), Lunar. Everything else is useless, even when I translate the difficult ones directly (try finding a good German translation for Beckoning Cat). Still, as long as everyone's clear on the standard names I think it can work just like formal and informal terms; your proper names for the comps, your slang names for your bros.
Watch me do a Klippe, or Cigar Balance, or Cliff Richard, or Lemming Stall, or whatever it's called, in ken grip:
