Meaning

verb hang loosely or laxly

verb be lazy or idle

originFrom Middle English lollen, lullen (“to lounge idly, hang loosely”), of uncertain origin; the Middle English Dictionary suggests a derivation from Middle Dutch lollen, lullen (“to doze; to mumble, talk nonsense”), though the words could merely be cognate. Compare modern Dutch lol (“fun”)), Icelandic lolla (“to act lazily”). See also lull.
