That hard drinking was introduced from Flanders and Holland, and other northern countries, seems probable from the derivation of many of the expressions used in carousing. The phrase of being "half-seas over," as applied to a state of drunkenness, originated from _op zee_, which in Dutch meant _over sea_; and Gifford informs us that it was a name given to a stupifying beer introduced in England from the Low Countries, and called _op zea_; thus Jonson in the Alchemist: I do not like the dulness of your eye; It hath a heavy cast, 'tis _up see Dutch_. An inebriating draught was also called an _up see freeze_, from the strong _Friesland_ beer. The word "carouse," according to Gifford and Blount, is derived from the name of a large glass, called by the Danes _ruuse_, or from the German words _gar_, _all_, and _ausz out_: hence drink _all out_. Nash, in the work above quoted, says, "Now he is nobody that cannot drink _super nagulum_, carouse the hunters' _hoope_, quaff _upsee freze crosse_, with healths, gloves, mumpes, frolickes, and a thousand such domineering inventions." The origin of these slang terms is not quite evident. Drinking _super nagulum_, or on the nail, was a northern custom which consisted in only leaving one drop in the cup, which was poured upon the thumb-nail, to prove that justice had been done to the potation or toast; and that, to use the language of modern drinkers, the glass was _cleared_. This custom is alluded to by Bishop Hall in his "Mundus alter et idem," in which the Duke of Tenderbelly exclaims, "'Let never this goodly-formed goblet of wine go jovially through me:' and then he set it to his mouth, stole it off every drop, save a little remainder, which he was by custom to set upon his thumb's nail and lick it off." In Fletcher we find the phrase I am thine _ad unguem_;
