DATY n. dining at the Y; cunnilingus. Editorial Note: The use of DATY seems to be closely associated with sex workers and sex work. According to Jonathon Green’s Cassell’s Dictionary of Slang (1998), the expression dine at the Y dates to at least as early as the 1940s and refers to “the conjunction of the thighs, plus a pun on the YMCA/YWCA.” Eric Partridge’s Dictionary of Slang and Unconventional English (Macmillan 1984, 8th edition, edited by Paul Beale), marks the term as Australian, though it is clearly now present in other Anglophone countries. Variants include eat at the Y, lunch at the Y, and love at the Y. (source: Double-Tongued Dictionary)
