In a manner lacking purpose or effectiveness; carelessly or without proper effort.
From 'feck' (Irish slang meaning 'effect' or 'value') plus the adverbial suffix '-ly'. The term gained popularity through Irish English and was widely used in the TV show Father Ted, though its original roots trace to dialectal usage.
This word perfectly captures how language spreads through pop culture—'feckly' became mainstream in English primarily because of a beloved Irish comedy show, showing how TV and media can resurrect and popularize obscure regional words.
