Word Origin & Etymology

Coined in 19th-century American English as a compound of 'show' and 'boat', referring to the flamboyant floating theaters that traveled the Mississippi and Ohio rivers. The figurative sense of a person who shows off emerged in the mid-20th century, inspired by the loud, attention-grabbing arrival of these vessels.
