Place it immediately after the confusing message or reaction it answers, so the reply lands as the punchline rather than an afterthought. Start with a WhatsApp message sound, then let it follow as the group's confused response, and finish with a short laugh sound if the chat keeps going.
关于此声音
A 5.6-second vocal clip that repeats the nonsense syllables oe oi oe eye eye in a steady chant, with no other words to follow. It feels deliberately absurd and light, like a private joke dropped into a conversation for no reason at all. Listeners tend to smile at its strangeness rather than try to make sense of it, which is exactly why it works as a quick interruption.
