fnap factor
Derived from fnappy. The level of euphoria you are experiencing, while on a feel-good substance. This incredible feeling is commonly brought on by a scheduled substance, more specifically a narcotic. Your level of 'feel good' is measured using the fnap factor, the 'fnappier' you are, the higher the 'fnap factor.'
