noun
To literally be the most average thing in the entire world. When something is jack average it is beyond "average", it is super average, uber average, extremely average...it is the king of average. Often disappointingly average but can be used to just describe something commonplace not necessarily a bad thing...it just is.
Considering the all the bloody hype, I expected the Warped tour to be sooooooo extremely freaking awesome, but it was just jack average. So I went home and punched a large hole in my wall.

Parkuru, "How's your day going?"

Kezric, "Meh...jack average...I'm going home to play Zelda...wanna come?"

Parkuru, "er...ok..."

Apr 27 Word of the Day
A horoscope so bad that it strikes fear into the heart of the reader, rendering them unable take action or make a decision on anything or to even leave the house. This is caused by a paralyzing fear that those actions or decisions may cause the predictions to come true.
After reading "There is a lot of uncertainty around financial transactions and investments right now, and the wrong decision could result in dire consequences" in his daily Horrorscope, Edward climbed back into bed, pulled the sheets over his head and remained there for the rest of the day.

Edward only had enough gas in his car to get to the gas station but was not sure if he had enough money in his account to pay for gas. His cell phone service had been cut off because his payments were in arrears, and since the only way he could be sure he had enough money (to pay for gas) would be to call the bank, he felt it best to hide in bed and hope his horoscope for tomorrow was more positive.
