Fat
Fats consist of a wide group of compounds that are generally soluble in organic solvents and generally insoluble in water. Chemically, fats are triglycerides, triesters of glycerol and any of several fatty acids. Fats may be either solid or liquid at room temperature, depending on their structure and composition. Although the words "oils", "fats", and "lipids" are all used to refer to fats, "oils" is usually used to refer to fats that are liquids at normal room temperature, while "fats" is usually used to refer to fats that are solids at normal room temperature. "Lipids" is used to refer to both liquid and solid fats, along with other related substances, usually in a medical or biochemical context. The word "oil" is also used for any substance that does not mix with water and has a greasy feel, such as petroleum (or crude oil), heating oil, and essential oils, regardless of its chemical structure.

Isn’t here any more.
All done with seeing her fat little form
Burst out of the basement door....”

“I pray we are still a young and courageous nation, that we have not grown so old and so fat and so prosperous that all we can think about is to sit back with our arms around our money bags. If we choose to do that I have no doubt that the smoldering fires will burst into flame and consume us—dollars and all.”
—Lyndon Baines Johnson (1908–1973)
