Etymology: "Kyais" is simply the plural of "kyai", a word borrowed into English from Japanese. In Japanese, "kyai" (気合い, 気合) is a term from martial arts and the performing arts for a sharp shout released to focus energy at the moment of a strike or a decisive movement. The word draws on "ki", a concept of vital energy or spirit, and "ai", meaning a meeting or union, so the literal sense is something like the joining of spirit with action. In English, the word has drifted from its dojo origins toward a looser sense: a quick, piercing cry of excitement, surprise, or delight. The plural form "kyais" treats these as countable bursts of sound, one shout after another. Its use in informal and performance contexts suggests that English speakers have taken the word for an expressive yelp rather than a disciplined martial cry.
