Gigglewater is a wizarding alcoholic beverage that was circulated in the United States. True to its name, Gigglewater may cause the drinker to laugh out loud when consumed. One known ingredient included Chortle extract, and it appeared to be colorless. Pinnock was one brand of Gigglewater sold in the 1920s.
Despite the American No-Majs enforcing Prohibition during the 1920s, Seraphina Picquery's stance on the matter was, as she famously put it to her Chief of Staff, that "Gigglewater is non-negotiable". One such establishment that served Gigglewater was The Blind Pig, where Jacob Kowalski tried it for the first time in 1926, experiencing its effects.
- Gigglewater or giggle water are slang words which really exist. Indeed, it's of the American slang to refer to an "intoxicating beverage, alcohol" as such during the Prohibition. It was especially used when describing champagne.
