The word used in some parts of Australia for a sweetened carbonated beverage.
I prefer to use the word 'pop'. It's short, sweet, and all encompassing: soda only refers to Cream Soda,
Club Soda, or
Jones Soda, all of which fit
under the umbrella of pop.
Lolly water is probably the least used word for these drinks unless there is one that I am missing.
