Derived from the mathematical term "hypotenuce," it is the longest side of the right-angle triangle formed by the standard emo haircut; the sloped line covering one or both eyes created by the backward, angular mullet favored by emo clones.
The length of an emo crybaby's emotenuce can be calculated with the formula A squared plus B squared equals C squared; C being the variable representing the length of the emotenuse.
much like the human "chemoreceptors" which measure hydrogen ion, CO2 and O2 in the blood, emoreceptors measure the amount of happiness or hurt circulating in the system.
After this break up, I really need to get out of town for a few weeks and hopefully reset my emoreceptors back to normal.
