Cracking means really good, brilliant, spot-on. You’ll hear it for anything that hits the mark: a cuppa, a bargain, a night out, even the weather if it behaves. It’s friendly, old-school British praise, not too gushy, just solid approval. Wallace and Gromit helped keep it in the national ear with that cracking cheese line.
"Went to Whitby for fish and chips, got dive-bombed by a cheeky seagull, but it was still a cracking day, proper reet."
