Discombobulation itself means to throw into confusion or disorder, often playfully.
So, if someone says "that was a real discombobulator," they're likely referring to something that caused a lot of confusion or disruption.
Here are some examples of things that might be called a "discombobulator":
* A confusing set of instructions: "Trying to assemble this furniture was a real discombobulator!"
* A sudden change of plans: "The weather forecast was a complete discombobulator, forcing us to cancel our picnic."
* A chaotic event: "That party was a discombobulator - there were so many people and loud noises!"
Remember, it's all about the playful and humorous use of the word.
