An afternoon of exceptional length, quality, or consequence — the kind that stretches so comfortably you forget what morning felt like. A mega arvo earns its name when the hours blur, the sun takes its time going down, the company is excellent, and no one checks the clock until well into the evening. In Australian usage it's applied with genuine appreciation: not every arvo becomes a mega arvo, but when one does, you know it. The measure is not duration alone but density of good times per hour.

That turned into a mega arvo — we sat at that pub table from 2pm until it was dark.
