Bungay

Go to Bungay with you!—i.e. get away and donʹt bother me, or donʹt talk such stuff. Bungay, in Suffolk, used to be famous for the manufacture of leather breeches, once very fashionable. Persons who required new ones, or to have their old ones new-seated, went or sent to Bungay for that purpose. Hence rose the cant saying, “Go to Bungay, and get your breeches mended,” shortened into “Go to Bungay with you!”
