- plural noun trousers. This word is the northern English version of the archaic ‘kicks’, heard in other parts of the country from the 17th century until the 1940s, but now obsolete. Liverpool mods of the mid-1960s used to refer contemptuously to ‘half-mast kecks’, that is unfashionably short trousers which flap around the lower calves or above the ankles. Strides was the slang synonym usually preferred further south. Underkecks are, of course, underpants, worn by either sex.
