The title Khikhikhikha is a transliteration of Russian onomatopoeia for giggling, written out the way a laugh sounds rather than as a formal word. Clips with this name circulate on soundboards and short video platforms as a generic laughing reaction, detached from any single show or character. Its short length and clear rhythm make it easy to recognise, save and reuse across chats and edits. It stays popular because the giggle is exaggerated enough to read as a joke cue even without context or subtitles.
