The title wtfisdis is the compressed internet spelling of what the fuck is this, a phrase typed in comments long before it became a reusable soundboard clip. With no single credited source attached to this version, it spread the way many reaction sounds do, through reshares as a shorthand response to posts that need no other explanation. Its longer runtime set it apart from short vine style reactions, giving editors room to cut their own timing. It remains in use because the question itself is universal, fitting fails, glitches, odd images and out of context videos.
