"Musk" originates from "muskrat". It was originally used to describe overly aggressive use of the mouth in sexual acts, such as biting. Musk has now expanded to mean going hard on anyone or anything. Much like "going HAM", musk is a state of mind. To musk is to fully rip into the situation and go 110%. One can either go musk, musk on, or simply musk, depending on context. Musk can also be interchanged with virtually any lyric in popular music to create a musk anthem.
