A mythical creature with the chinchilla sized head of a chinchilla, chinchilla sized feet, and the full sized body of a unicorn. (Incredibly aggressive)
Person 1: Corinne! I'm such a little dirty flemboy, please spit in my mouth!
Person 2: Ew! You're so nasty! But... we have been together for a long time... So if it makes you happy... I guess I could...
A flerb is a form of measurement. The equation for flerbs changes daily. They are so many variables in the equation that there is no way for you to figure out what those variables stand for, thus making the measurement useless. The measurement might be useless, but flerbs are vary useful for writing on math tests when you don't know the answer. That number of flerbs might be equal to the answer of the question.
"Today's equation for flerbs is - (a + b) - arc length of semicircle x volume of box."
The variables aren't defined at all. You have no idea what a and b stand for, or what semicircle I'm talking about, or what box I'm talking about.
A more appropriate term for the slack-jawed mental midgets that failed all science classes so hard that they believe is an idea debunked over 2000 years ago that the planet we live on is flat!
