What does "filthy" mean in Australian slang?

In Australian slang, "filthy" means extremely angry, annoyed, or upset, often used when someone is very frustrated about a situation, result, or unfair outcome. It is used in informal Australian English, especially in everyday conversation, sports commentary, and casual storytelling, where strong emotional reactions are commonly described with exaggerated terms. The usage developed as an extension of standard English "filthy," which originally meant dirty or unclean, but in slang it shifted metaphorically to describe a "dirty" emotional state, implying intense irritation or resentment.

Examples
He was filthy when he missed the train.
