As pronounced in a British accent, the word Gosiaco originally came from the expression "Go, shocker!" This came as a result of several attempts by British street-performing magicians to jump into a pool of fish, while the gathering crowds would scream the said expression. Widespread usage of the term has lead to a total restructuring of the expression as a whole, amalgamating both words into a single word.
