Reek-ter Scale

A scale used to measure how horrible something smells (reeks). Similar to a Richter scale that measures the strength of earthquakes, the Reek-ter scale measures the level of disgust generated by a particular smell.

Damn it Joe! Stop farting! Your ass is measuring an 8 point 0 on the Reek-ter scale. If that shit gets any worse, you're gonna take 5 years off my life.
