nipping
n.— «Players are often extraordinarily generous, buying drinks and not merely to make opponents drunk. They are big on “nipping,” and this is no racist slur on the oriental client base: it is poker parlance for lending money, even to strangers.» —“You bet I’m heading for Manchester” by Jasper Gerard Telegraph (United Kingdom) Feb. 1, 2007.
