Trying to find a sound

So this may be a bit odd but I’m trying to find a specific sound on TikTok and have no clue of how to even try to find it. If I remember right, it’s like a high pitched voice that is going “ne ne ne” and it makes me think of someone who is talking so fast about something they are interested in that no one can understand them (unless I imagined it, lol ¯_(ツ)_/¯)
