The repeated phrase in the original title is Khmer for eating, written as yum yum yum, which explains the clip's focus on chewing as a joke rather than a song. Short eating sounds like this spread through short form video and soundboards because they are language free and instantly readable as hunger, greed or enjoyment. Creators reuse the same exaggerated munching over restaurant clips, cartoon food and prank meals, so the meaning stays clear even without context or a known source performance behind it.
