The term 'Like a Quark' is a reference to the subatomic particle known as a quark. Quarks are the smallest known particles and are believed to be the building blocks of matter. They are found in the nucleus of atoms and are held together by the strong nuclear force. Quarks come in six different types, known as flavors, and can combine to form larger particles such as protons and neutrons. The term 'Like a Quark' is used to describe something that is very small or insignificant.
