Fallon is a strong girl. Not looking for love at a young age, she loves to be outside. Protective of her friends and not afraid to speak her mind, she is BLUNT AS HELL. If you have a Fallon as your best friend, you are blessed. She is an individual, independent, and enjoys the simple life, such as picnics, long horse ride on her ranch, and spending time with the people she loves. If you have a Fallon in your life, hold on to her for as long as you can, without making her mad.
Bully: Hey, why do you have such a wierd haircut.

Fallon: You have exactly 3 seconds to run before I drive a knife through your heart.

v. to fallon = to laugh at one's own joke, especially during the very act of telling that joke.

Origin: derived from Jimmy Fallon, American comedian (b. 1974 in NY)
Sarah couldn't manage to describe Isaac's hysterical story. She kept fallonning and then would try to start over. The 20-second story took about 4 minutes, most of which was her laughter.

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.
Hag: "What do you think of my new boyfriend?"
Fag: "He's about 3 fallons, maybe 4 after a few drinks."
