Place it right after the confusing text message appears on screen, then follow it with a bruh reaction for a double take, or lead into it with goofy ahh sounds to set up the chaos before the punchline lands.

This two-second clip is a playful vocal bit built around a repeated eng-eng-eng chant that lands on a cheeky pushy poop line. It sounds deliberately goofy and a little rude, the kind of nonsense that makes a group chat laugh because it makes no sense at all. The silliness is the point, turning a tiny throwaway phrase into a quick jolt of chaotic, childish humour.
