The word "JEAH!!!" is an interjection that can often be used in the place of "Yes" by individuals who prefer to answer simple questions with extremely loud and inappropriate responses.

"JEAH!!!" can also be used in agreement of something that is not a "yes or no" question, similar to saying "that's awesome." Often this interjection can be used at random intervals when no questions are even asked or in the middle of an awkward silence.

For added emphasis, more consonants may be added to the beginning of the word. The longer the "build-up" to the "climax," the greater the effect.
Thus,
"JEAH!!!"
becomes
"FVJEAH!!!!!"
or even
"CHVSHBVWDTRVDSFKVVJEAH!!!!!!!!!!!!!!!"

It is important to not confuse "JEAH!!!" with its cousin "MYAH!" which has similar useages, but is of different origins.

Although the true history of the word "JEAH!!!" is shrowded in mystery, it appears to be either a degradation of the word "Cheah," which is believed to mean "Cheers," or it is simply a rebellious form of the word "Yeah," coming from "Yes." Scholars are still in debate to this day on the matter.
