Walk where we will, we cannot help hearing from every side a phrase repeated with delight, and received with laughter, by men with hard hands and dirty faces, by saucy butcher-lads and errand-boys, by loose women, by hackney-coachmen, cabriolet-drivers, and idle fellows who loiter at the corners of streets. It seems applicable to every circumstance, and is the universal answer to every question; in short, it is the favourite slang phrase of the day – a phrase that, while its brief season of popularity lasts, throws a dash of fun and frolicsomeness over the existence of squalid poverty and ill-requited labour, and gives them reason to laugh as well as their more fortunate fellows in a higher stage of society.
Many years ago the favourite phrase was Quoz. When vulgar wit wished to mark its incredulity, and raise a laugh at the same time, there was no resource so sure as this popular piece of slang. When a man was asked a favour which he did not choose to grant, he marked his sense of the suitor’s unparalleled presumption by exclaiming Quoz! When a mischevous urchin wished to annoy a passanger, and create mirth for his comrades, he looked him in the face, and cried out Quoz! and the exclamation never failed in its object. When a disputant was desirous of throwing a doubt upon the veracity of his opponent, and getting summarily rid of an argument which he could not overturn, he uttered the word Quoz, with a contemptuous curl of his lip and an impatient shrug of his shoulders.
