Where is it going to sit? Are you suggesting that it's not possible to clear it out of the trap?
Can you turn the dick off for a minute, or is this another one of those cases where you realize that you misspoke and then argue minutiae?
This random plumber I googled says this:
"Many people believe that pouring cooking oil or grease down a drain is harmless because these items are liquids. However, the problem is that oils do not behave the same way other liquids do. Oil or grease may look like it goes down the drain fine. However, once it cools down, it can cling to your drainpipes. Eventually, the coating builds up over time, causing severe blockages, and clogged drain pipes.
Oils are also denser than water and other liquids. As a result, oil will float around, accumulating over time. The end result is that you could end up having a clogged drain and need to call a plumber in Greenville SC to come out and unclog it.
Go Green
A clogged drain is not the only thing that you should be worried about. If you regularly pour vegetable oil down your drain, it will harm the overall water supply by polluting it over time. One small way you can help protect your local environment is by properly disposing your cooking oil.
So what do you do with waste oil and grease?
Pouring oil and grease down your drain or garbage disposal is certainly a quick way to get rid of it. However, you should now understand that it is not a really good solution. The best option is to use the trash can! The proper way to dispose of cooking oil is to pour it in a container and dispose of it in a trashcan."
Tl;dr Don't dump oil down the drain it clogs and enters the water supply.
