* The Korean language uses a different alphabet from English so translated spelling and pronunciations will vary. Because the Korean language uses discrete syllables they are divide with a forward slash in the Gothppentix to aid in pronunciation.

** Korean slang, in this case, is the use of English words in a way that is unique to Korean pop culture.

*** Sayings that are, as far as I know, unique to the GothyCrumpets and/or Lookzens.
