6-10

term used to describe something that is an over exaggeration. When a story, or fact, is taken and stretched in truth to form something new. Directly compairing the exaggeration to the act of rounding seen in mathmatics- (i.e.) taking the number "6" and rounding it to a "10." similar to the term 6g

"That statement is a total 6-10; Ken hasn't been offered a job yet..he's going in for the interview this week."

6-10 Syndrome 

Your team wins enough games to string you along through Week 10 or so with hope of the playoffs, only to swiftly extinguish said hope with inept decision making down the stretch. They finish 6-10 (5-11 or 7-9 are also acceptable symptoms) and get the 6th to 10th pick in the Draft. You know, just low enough where he's not a franchise changer and they could still screw it up, but high enough where the cap implications set you back for a few more years. You, the victim, go into the draft wrongly believing they are "a piece or two away". The cycle repeats.

The 6-10 syndrome was clearly at epidemic levels in Buffalo as, year after year, season ticket sales increased to record levels despite a sub-par on the field product.
