"Impetuous, precipitate; reckless; headstrong", Late 18th cent.; earliest use found in Robert Burns (1759–1796), poet. Origin uncertain. Perhaps from Scots ram-, intensifying prefix + stam to walk with a quick heavy tread; compare earlier ram-tam. In English regional (south-east midland) use apparently of different origin: perhaps from ram + stam; compare English regional (Cornwall) stam-bang (adverb) headlong (attested from 1846 onwards).[ram-stam etymology, ram-stam origin, 英语词源]
