The word "lubing" is commonly used as a shortened version of lubrication. When we talk about lubrication, we generally refer to the process of adding a substance to reduce friction between two surfaces. However, there are several other synonyms of the word "lubing" that are used in different contexts. Some of these synonyms include greasing, oiling, slicking, waxing, and smoothing. Greasing specifically refers to the process of using grease to reduce friction, while oiling involves using oil for the same purpose. Slicking implies making a surface smooth and reducing friction between them. Waxing is used to treat surfaces with wax to make them smoother, while smoothing involves making the surface smoother by removing roughness.
