A fallon is a unit of measurement used to describe how sexually attractive a man is. One fallon is equal to Jimmy Fallon. This unit is typically used by homosexual men. The fallon system has very few rules. To be a valid measurement, it must be a positive number between zero and 10. Fractions and decimals are permitted (a person can be half a fallon) but nobody can be zero fallons. Generally, a 10 is not given as it implies the perfect man, but is valid. The fallon number system is metric, so prefixes may be added to the unit.
