A moron in a hurry
"A moron in a hurry" is a phrase that has been used in legal cases, especially in the UK, involving trademark infringement and passing off. Where one party alleges that another (the defendant) has infringed their intellectual property rights by offering for sale a product that is confusably similar to their own, the court has to decide whether a reasonable person would be misled by the defendant's trademark or the get-up of their product.
