Doing
everything possible to fail miserably at any task after success appeared inevitable. Snatching defeat from the
jaws of victory. Being one's worst enemy. A reference to the tendency of the Michigan State Football team to dominate 3 1/
2 quarters only to implode and give the game away to their opponent, resulting in a frustrating defeat.
Example 1: Bill overachieved all year to get that promotion, but got fired for sending that
joke about his boss to the whole company. Bill really Pulled a Sparty.
Example
2: That girl has been into Jeff all night. I
hope he doesn't Pull a Sparty and tell her about his Dungeons and Dragons collection.
