The phrase is everyday Dutch, so its spread online has less to do with a single source and more to do with how instantly it translates as a reaction. Short voice clips like this circulate on soundboards and in edit communities because the meaning is clear even to listeners who do not speak Dutch, helped by the flat delivery and two second length. It has become a reusable shorthand for calling something illogical without starting a debate, especially in meme edits, reaction compilations and chat soundboards.
About this sound
A short Dutch voice clip saying klinkt onlogisch, meaning sounds illogical, used as a dry reaction to nonsense, plot holes and bad arguments.
A two second spoken Dutch phrase delivered in a flat, matter of fact tone: klinkt onlogisch, literally sounds illogical. The line lands like a calm verdict rather than an argument, which is why it works so well as a punchline. Drop it after a contradictory statement, a broken plan or a piece of logic that collapses on contact, and the deadpan delivery does the judging for you. It needs no setup and no explanation, just the brief pause before it to let the absurdity hang in the air.
