The go-to insult used by
crazy old ladies in Australia who think that they own property which they do not, and falsely try to prevent people with jobs, belts, children, pets, and especially bald people, who they also often refer to as "baldy arse" from entering the premises.
The word "worm" is intentionally vague and ineffective as an insult, as these
crazy old women tend to know nothing about the person, so will just fire
random insults at members of the public hoping that one of them hits
home, with "worm", according to professional research, being a fan favourite.
Other insults used by these women are insulting the person at their inadequacy with dealing with their children and their pets, the word "turd", and insulting the person's (if that person is a man) genitalia, with the most infamous usage of this being from the great
Queen Del Pufflet of Neutral Bay II, saying to the baldy arse at the
time "go and tweak yer bloody dirty old crappy
penis"
Person: I can see you've clearly spawned a couple
kids, have you?
Crazy Lady: Heh, none of your business. You worm of a thing.
Person 1: I'm taking that as a zero.
Crazy Lady: You worm of a thing.
Crazy Lady: You bloody worm, GET OFF MY PROPERTY!
Crazy Lady: Heh, get back to it... WORM!
Person: Is that the best insult you've got? Is that the best you can come up with?
Crazy Lady: You're a worm.
Person: You've said.
Crazy Lady: You're an inadequate worm.
Person: I know.
Crazy Lady: You're inadequate with the
dog, and you're inadequate with the child.
