A curse in sports
where a small box of information known as a stat graphic appears on your TV explaining a current streak of some sort. After the stat graphic is no longer on your TV, the streak is snapped.
A stat graphic reads:
Bruins are the only team not to allow a power play goal in the playoffs. Two minutes later, the Bruins allow a power play goal in the playoffs.
If you are a Bruins fan, you have just fallen victim to the stat graphic curse.
