SISERARA, a hard blow.—_Suffolk._ Moor derives it from the story of Sisera in the Old Testament, but it is more probably a corruption of CERTIORARI, a Chancery writ reciting a complaint of hard usage. SIT UNDER, a term employed in Dissenters’ meeting houses, to denote attendance on the ministry of any particular preacher. SITTING PAD, sitting on the pavement in a begging position. SIT-UPONS, trousers.—_See_ INEXPRESSIBLES. SIVVY, “’pon my SIVVY,” _i.e._, upon my soul or honour. Corruption of _asseveration_, like DAVY, which is an abridgment of _affidavit_. SIXES AND SEVENS, articles in confusion are said to be all SIXES and SEVENS. The Deity is mentioned in the Towneley Mysteries as He that “sett all on seven,” _i.e._, set or appointed everything in seven days. A similar phrase at this early date implied confusion and disorder, and from these, _Halliwell_ thinks, has been derived the phrase “to be at SIXES AND SEVENS.” A Scotch correspondent, however, states that the phrase probably came from the workshop, and that amongst needle makers when the points and eyes are “heads and tails” (“heeds and thraws”), or in confusion, they are said to be SIXES AND SEVENS, because those numbers are the sizes most generally used, and in the course of manufacture have frequently to be distinguished. SIXTY, “to go along like SIXTY,” _i.e._, at a good rate, briskly. SIZE, to order extras over and above the usual commons at the dinner in college halls. Soup, pastry, &c., are SIZINGS, and are paid for at a certain specified rate _per_ SIZE, or portion, to the college cook.—_Peculiar to Cambridge._ _Minsheu_ says, “SIZE, a farthing which schollers in Cambridge have at the buttery, noted with the letter _s_.” SIZERS, or SIZARS, are certain poor scholars at Cambridge, annually elected, who get their dinners (including _sizings_) from what is left at the upper, or Fellows’ table, free, or nearly so. They pay rent of rooms, and some other fees, on a lower scale than the “Pensioners” or ordinary students, and answer to the “battlers” and “servitors” at Oxford. SIZINGS, _see_ SIZE. SKATES LURK, a begging impostor dressed as a sailor. SKID, a sovereign. Fashionable slang. SKIE, to throw upwards, to toss “coppers.”—_See_ ODD MAN. SKILLY, broth served on board the hulks to convicts.—_Linc._ SKILLIGOLEE, prison gruel, also sailors’ soup of many ingredients. SKIN, a purse. SKIN, to abate, or lower the value of anything; “thin SKINNED,” sensitive, touchy. SKIN-FLINT, an old popular simile for a “close-fisted,” stingy person. SKIPPER, the master of a vessel. _Dutch_, SCHIFFER, from _schiff_ a ship; sometimes used synonymous with “Governor.” SKIPPER, a barn.—_Ancient cant._ SKIPPER IT, to sleep in the open air, or in a rough way. SKIPPER-BIRDS, or KEYHOLE WHISTLERS, persons who sleep in barns or outhouses in preference to lodging-houses. SKIT, a joke, a squib.
