@Setanta,
Can't answer all those questions but :-
Wowser I always related to "wow" then adding the ending as slang BUT, not the case. It's Australian slang but isn't aimed at only women. It relates to someone as a derogatory word describing a person who saps all the fun out of any given situation.
pies: - Pie Floater. Meat pie with pea soup and tomato sauce. In my 20's I admit, to having a couple. Really tastes good looks disgusting. So I might as well add a disgusting photo.
We used to call them pie carts
Magpies.
Meet "Flappy" that's because he flaps his wings at us to let us know it's him to get his bit of mince:)
Black and white Magpies are an Australian species of maggies and New Guinea, though there are several species all different colours across the World.
They are mostly male and they swoop humans if 100 metres near their nests but are part of the Crow family and Australian footballers have teams called "The Crows" and "Maggies" go the maggies. A lot of "us" Aussies, can't help ourselves and feeds these birds. They are highly intelligent.
Flappy and his lot, are the smaller versions here. We call them piking shrikes.
The large magpies look like this below:- We have two babies at present that come in the morning with the "parents" to also get food. I must work harder, the costs of feeding all these pests is a lot ..
