The exact original recording behind this clip is not widely documented, so it circulates mainly as a short soundboard sound rather than as a clip from a well-known show or film. Its appeal comes from the line itself, a simple way of saying this is my friend, which creators can reuse for almost anyone or anything they want to present with affection. Because the wording is so general, it works across friendship videos, pet edits, and playful introductions, and it keeps being reused whenever a creator wants a quick, warm reveal without a long explanation.
