Place it immediately after the accusation in your edit, then follow it with a fart with reverb for the contradiction, and finish with a bruh when nobody believes the denial.

This is a short spoken Dutch meme line, just under three seconds long, in which Joep insists he did not let a fart slip out. The flat, deadpan denial makes the claim sound even less believable, giving the clip a cheeky, awkward humour that lands best when everyone already knows the truth. It works as a quick, knowing joke about blaming someone else.
