dope

I

Australian Slang

1. marijuana or hashish;

2. any drug, especially a narcotic;

3. stimulating drug illegally given to a racehorse to either induce greater speed or impair its performance;

4. information or data (originally used in horseracing contexts, i.e. the information about which horses have been doped or not);

5. stupid person (possibly a separate word; originally found in British dialect (Cumberland; mid-19th C.); in this dialect 'dope' is a variant of 'dowp' - 'carrion crow', which conceivably could be used in a derogatory manner to refer to people);

6. affect with dope or drugs;

7. very cool and sophisticated: 'the dopest nightclub around' (recent (1990s) borrowing from the US) (all senses, except 4, originally US slang; originally (early 19th C.) meaning 'sauce', 'gravy', from Dutch 'doop' = 'dipping sauce')
