Me and my girlfriend have been having a discussion for a whole day about whether or not fats are oils. We’ve googled it and the only facts we found is that fats are solids and oils are liquid, we also found that they are the same, we both agreed on that. But she also claims that oils are necessarily plant-based, which I don’t agree with.
She’s studying biology, and knows the chemistry and the proper names for things, while I have less scientific know-how, but know damn well you can use bacon fat as cooking oil. I don’t know if l’m right, moreover, I don’t know how to explain that she is wrong (if she is). Please help.

The general structure is called a “triglyceride” and if the specific structure is a solid at room temp it’s a fat and if it’s a liquid at room temp it’s an oil.
It happens that animal triglycerides are usually solid (animal fat) and plant triglycerides are usually liquid (vegetable oil).
Fish oils though are animal triglycerides that are liquid at room temp.
