An outrageous thing is something that's really shocking or extreme.
When people say that something is outrageous, they usually mean it's going way beyond what's normal or acceptable. They might talk about an outrageous price for a product, meaning it's ridiculously expensive. Or they could call someone's behavior outrageous if it's extremely reckless or hurtful. In general, the word "outrageous" is used to express strong surprise or criticism, like when you hear about a politician doing something really unethical.
Violating morality or decency; provoking indignation or affront.
