Like a "Black Sawn Event" but way less significant. When something seemingly nice turns straight negative, in an unexpected way, or in a scale or manner that is unanticipated.
"Hey, this summer rain is really nice... I wonder how long it will last..." Check weather... "Oh no, there is a flash flood and tornado warning that was just issued! This is a real Black Duck Event."

Get the Duck childmug. The best Muscovy Duck that you will ever see in the world. It is so cute that it always looks at you before you can look at it. My mom always hits it and is always arguing about how much it poops however, I always try to protect the duck because of its cute face and body. The boy duck always bites my mom and the girl duck doesn't bite my mom. Both of the ducks have never bit me. In the end, the ducks are the most beautiful, friendliest, and cutest animals in the entire world

Get the Thara (Duck)mug. From poron: in social media, a Post-and-Run Moron who insincerely makes a moronic social media post, often claiming expertise they do not have, for attention with no intention to respond; + Duck here being a contraction indicating Dunning Kruger syndrome (a type of cognitive bias in which the person believes that they are experts in a topic in which they in fact know almost nothing. Essentially, a social media poster without the insight or knowledge needed to recognize their own incompetence, posting ludicrous claims to seek attention and responses.
You have posted a moronic proposition in a subject of which you know nothing, just to seek attention. You are just a Poron's Duck.
