The act of boasting about your sports team's previous accomplishments when said sports team is faced with defeat and adversity in the current season. Usually done as an act of self-consolation, or when backed into a corner in a debate/argument.

Those guilty of Ninering are often fans of historically successful franchises and cannot deal with losing in a secure and gracious manner, leading to petty gloating.
I commented to Jeff that Colin Kaepernick seems to be struggling against higher quality secondaries this season, and he got snippy and started ninering about one of their 5 Super Bowls from 20 years ago.
