An exclamatory fixed phrase expressing a mix of surprise and mild irony. Often signals that the speaker finds a situation remarkable or slightly absurd. Common in everyday conversational speech.

Used when someone wants to firmly check another person's behaviour or ambition. Implies asserting authority or setting a limit. Not aggressive in tone, but direct.

Fixed simile meaning something spreads or moves with explosive speed. Used for rumours, trends, news, or problems. The literal meaning (gunpowder) would not lead a learner to this figurative use.

Literally means to feel/probe something, but in conversation it means to cautiously gauge someone's opinion or reaction before committing to a position. A false friend trap for learners who know 'to tally' or 'to estimate'.
