I thought I had trapped wind. Turns out it was Ions. After wearing one of these bracelets from Team Ionic, I am happy to report sweet **** all. As I would get a better result from chugging a pint of unicorn farts.
There’s also gyppy, as in gyppy tummy, a term for diarrhoea mostly known in the UK and Commonwealth countries. This does have the same origin as gypsy — a mangled version of Egyptian. Gyppy tummy is noted by Eric Partridge as World War Two services slang for the ailment suffered by British forces in the North African desert campaign, and it was a phrase common in Britain after the War. It seems certain that gyppy was influenced in its creation by the pain sense of gyp, but also built on gyppy or gippy, a slang term for an Egyptian that can be traced back to Lord Kitchener’s army in Egypt in the 1880s and 1890s.
