"Putting over" is a slang term that means successfully conveying an idea or completing a task. Its antonyms, on the other hand, are words that describe the opposite of that meaning. Some of the antonyms for "putting over" are failing, botching, bungling, floundering, and fumbling. If someone is failing to put something over, they are not able to successfully convey their message. Botching a task means that it was not completed effectively. Bungling is similar to botching, but it implies more of a clumsy or incompetent execution. Floundering is struggling and not making progress, while fumbling refers to making mistakes or experiencing difficulties in carrying out a task.
