Place it right after the unfair food split is shown, then follow it with Bruh for a short reaction before the scene moves on. If the scene continues, add Baby Laughing Meme after the reply to close the joke without crowding the cucumber line.
About this sound
This is a short spoken Lithuanian meme line, 'Viena agurka palieki man,' delivered as a single voice clip built around one small food complaint. It feels petty, playful and deliberately dramatic, like a friend making a tiny slight sound much bigger than it is. The line lands best as a quick, knowing reaction to being short-changed on something small.
