Someone who spoils the fun; a goody-two-shoes.

Australian slang used to describe someone who is considered to be not fun, i.e. overcomplicates matters, doesn't drink an amount of alcohol deemed socially appropriate, disagrees with the sentiments of a group. Specifically the term is likely to be applied to a man who is viewed to be judging the morals of his accusers and/or setting himself apart as morally "better" than others.

It's pretty dated, but not entirely out of use.

Australians very much like to believe that we are a classless society. Therefore, depending on context, "wowser" could be more offensive than well-known swear words.

Its just like wow but more like if your sarcastic and surprised at the same time

A term to express excitement, anger, sadness, pretty much can be used to express any emotions and used in any type of conversation
