Boatayy is a hybrid of
Boat and a play on the word 'Party' as the Upper class gentlemen around the Wiltshire province of Salisbury, UK, may seemingly pronounce the word Party as 'Partayy', also there love affair of boats in which they attend meetings to talk about Sailing while enjoying a nice Bacardi and Coke, so combining the two words together into "Boatayy" is slang for the Upper Class Gentlemen to
go enjoy
homosexual activities while Sailing across the Channel to France, Typically
heard across the Villages surrounding Salisbury, for example; Downton, Fordingbridge and Woodfalls.
