Odd man out, a street or public-house game at tossing. The number of players is three or more. Each tosses up a coin, and if two come down head, and one comes tail, or vice versâ, the ODD MAN loses or wins, as may have been agreed upon. Frequently used to victimize a “flat.” If all be alike, then the toss goes for nothing, and the coppers are again “skied.” It is easy for two men to arrange matters beforehand at this game, and so swindle a third.

Odd man, a man who trains in company with a boat’s crew, so that in the event of any one falling ill the seat will be fairly occupied.

Odds, a phrase equivalent to “consequence;” “what’s the ODDS?” i.e., what is the expected result? “It’s no ODDS,” i.e., of no consequence. ODDS, in sporting phraseology, refers to the proportions or differences of a bet. One bookmaker will lay ODDS of “six to one” against such a horse winning; whilst another, more speculative, or in the receipt of a first-rate “tip” (information about the horse in question) will lay “eight,” or even “ten to one.”

Od rot it (Colman’s Broad Grins), DRAT IT, OD’S BLOOD, and all other exclamations commencing with OD, are nothing but softened or suppressed oaths. Od is a corruption of GOD, and DRAT of ROT.

Old dog, a knowing blade, an experienced person. Butler uses the phrase, Hudibras, part ii. canto iii. 208, where it was said of Sidrophel, “And was OLD DOG at physiology.” An Irish proverb says, “OLD DOG for hard road,” meaning that it requires an experienced person to execute a difficult undertaking.

Old salt, a thorough sailor.

Old Tom, extra strong gin; sometimes termed CAT’S WATER. Various reasons are given for the use of the words Old Tom. The distillers have the sign of a tom cat on their illuminated placards. The origin of the phrase is, however, in the fact that the managing clerk of a once celebrated “gin-spinning” firm, who was known as Old Tom, used to keep a special bottle of extra good stuff with which to regale customers when they settled their accounts. To get a drink of Old Tom’s was then a great favour. Gradually the title became popular as representing very good strong gin.

Over, generally used in connexion with come, as, “He came it rather strong OVER me,” i.e., tried to intimidate or compel me. The same phrase would also be used to imply that an excess of flattery or praise was being employed for a similar purpose, but that the adulation was being “laid on a little too thick” to be considered genuine. Also used thus sometimes: “You mustn’t come Shakspeare OVER me,” i.e., “you mustn’t assume an air of immeasurable literary superiority OVER me.” “You mustn’t come Rothschild OVER me,” &c.

Over, in cricket, four balls delivered from one end to another. After an OVER has been bowled, the fielders, wicket-keepers, &c., change ends, and the bowling goes on from the recent batting wicket. A MAIDEN-OVER is an OVER from which no runs are obtained. Four balls is the regulation number to an OVER in all important matches; but little clubs and practice elevens suit their own convenience.
