gardyloo

A cry used to warn passersby before emptying a vessel of wastewater into the street.

[A]ll the chairs in the family are emptied into this here barrel once a-day; and at ten o'clock at night the whole cargo is flung out of a back windore that looks into some street or lane, and the maid calls Gardy loo to the passengers, which signifies, Lord have mercy upon you! and this is done every night in every house at Haddingborough; so you may guess, Mary Jones, what a sweet savour comes from such a number of profuming pans […]

It would, in fact, seem as if a tacit agreement existed, that so soon as St Giles' clock struck ten, the windows were simultaneously opened for a general discharge (which, in 1745, must have rather alarmed Prince Charles' followers, when they had possession of the town), and the streets and closes resounded with one universal cry, Gardyloo! Dr Jamieson, in his Dictionary, gives the word as Jordeloo: I doubt if any such word was ever used; but in his Supplement the learned Doctor properly assigns it to the original French phrase, Gare de l'eau—Beware the water […]

A cry of “gardyloo”.

What do the polished inhabitants of Carrubber's close care for all the taunts that can be uttered by the mouths of all the tobacco-chewing, bacon-eating bagmen who chatter no intelligible language of any country, about "gardy loos," and Caledonian cremonas?

Notwithstanding the repeated proclamations of successive magistrates against depositing filth on the streets and closes, and against throwing soil and refuse over the windows, – emphasised as these proclamations were by threats of fines, imprisonment, the pillory, whipping, and banishment, – the practice was continued far into the last century; and contemporary writers represent the sounding of ten o'clock from the steeple of St Giles' to have been the signal for a general and simultaneous discharge from the windows of every house, amid a chorus of "Gardyloos."

An act of discarding waste or some other substance from a height. Also attributive and figurative.

I believe the auld women wad hae greed, for Lucky Mac-Phail sent down the lass to tell my friend Mrs Crombie that she had made the gardyloo out of the wrang window, out of respect for twa Highlandmen that were speaking Gaelic in the close below the right ane. […] Mrs Glass, who had been in long and anxious expectation, now rushed, full of eager curiosity and open-mouthed interrogation, upon our heroine, who was positively unable to sustain the overwhelming cataract of her questions, which burst forth with the subliminity of a grand gardyloo […]

Siobhan Clarke looked like she'd stepped under a gardyloo bucket. She tried not to show it, and smiled whenever she saw him looking in her direction, but there was definitely something up with her.

Caution, warning.

Released but a few weeks before Gremlins, this film drew only foreshadowings of concern that spiraled up into hysterical gardyloos when Gremlins made its debut.

And now, to be usherhandled up the aisle, my ear pincered excruciatingly, my dear sweet Granny kvetching along behind, intoning half-Yiddish gardyloos about my certain future as either a demented hunchbacked bell-ringer, or a Cossack love-slave ... how ignominous!
