catch as catch can

By any method that can be used; without any specific plan or order. Variants of this term go back as far as the fourteenth century (“Was none in sight but cacche who that cacche might,” John Gower, c. 1394) and appeared in John Heywood’s 1546 collection of proverbs (“Catch that catch may”). More specifically, it is the name of both a children’s game and a style of wrestling (also called freestyle) in which the wrestlers may get a hold on each other anyhow and anywhere.
