Because the clip is only about two seconds long, it circulates mainly as a quick reaction sound rather than a longer scene, and its appeal comes from the specificity of the name and situation. Naming Phil directly makes the line feel like a message passed on second-hand, which is why it works in short-form edits and jokes about parents learning something they would rather not know. The humour lies in recognition: almost anyone can picture the awkward moment that follows such a revelation.
