de•gen•er•a•tion(dɪˌdʒɛn əˈreɪ ʃən)
go to hell in a handbasket To indulge in petty or sporadic dissipation; to carouse occasionally, in a small way; to degenerate bit by bit; gradually to go downhill morally. This slang expression is often used to describe typically adolescent anti-social behavior, usually of a temporary nature. However, it sometimes carries connotations of more serious and permanent moral decline. Its origin is unknown but it is interesting to speculate that it may be related to go to heaven in a wheelbarrow ‘to be damned’—handbasket replacing wheelbarrow to indicate the relative small-ness of one’s sins; hell replacing heaven to accommodate more literal minds. See go to heaven in a wheelbarrow, PUNISHMENT.
go to pot To deteriorate, to go downhill, to degenerate, to fall into a state of disuse or ruin. Although the exact origin of this expression is unknown, it may be related to the earlier phrase go to the pot, literally ‘to be cut into pieces like meat for the pot,’ and figuratively ‘to be ruined or destroyed.’
If it were to save the whole empire from going to pot, nobody would stay at home. (Pall Mall Gazette, February, 1884)
go to rack and ruin To degenerate, to deteriorate, to decline, to fall apart; also to go to rack and to go to ruin. Rack ‘destruction’ is a variant of wrack and wreck. The expression dates from at least 1599.
Everything would soon go to sixes and sevens, and rack and ruin. (Elizabeth Blower, George Bateman, 1782)
go to the dogs To degenerate morally or physically, to deteriorate, to go to ruin. The expression, which dates from at least the early 17th century, is thought to have come from the earlier Latin phrase addicere aliquem canibus ‘to bequeath him to dogs.’
Rugby and the school-house are going to the dogs. (Thomas Hughes, Tom Brown’s School Days, 1857)
on the high-road to Needham On the road to poverty or ruin; on the skids; suffering a mental, moral, or financial decline. This British expression, of infrequent occurrence, simply puns on need without reference to a specific locality.
on the skids On the road to poverty, ruin, disgrace, or oblivion; in a state of rapid deterioration or decline. The skids as denotative of a moral condition may derive from Skid Row. (See LOCALITY.) It appears frequently in longer phrases such as hit the skids ‘start on the downward path’ or put the skids under ‘cause the ruin or decline’ of a person or plan.
By 1929 Bix [Beiderbecke] was on the way down—not yet on the skids, but the good time and the big time was behind him. (Stephen Longstreet, The Real Jazz Old and New, 1956)
the seamy side The most disagreeable, unsavory, and offensive aspect; the sordid, perverse, degenerate, or immoral features. Literally, the seamy side refers to the wrong, or underside, of pieced fabric which shows the rough edges and seams of an otherwise acceptable article of clothing, tapestry, etc. The figurative use of the seamy side was pioneered by Shakespeare:
Oh fie upon them! Some such squire he was
That turned your wit the seamy side without,
And made you to suspect me with the Moor.
(Othello, IV, ii)
A commonly used derivative is seamy.
