Word Origin & Etymology

The insect sense is a mid-19th-century American shortening of 'cockroach', derived from the Spanish 'cucaracha'. The fish sense stems from Old French 'roche', which is of Germanic origin. The slang term for a marijuana cigarette butt emerged in the 1930s, supposedly due to its visual resemblance to the insect.
