Jinxed

Jinxed is a Fallout, Fallout 2 and Fallout Tactics Trait.

The good thing is that everyone around you has more critical failures in combat, the bad thing is - so do you! If you or a non-player character have a failure during combat, there is a greater likelihood that the failure will be upgraded (or is it downgraded) to a critical failure. As you can read affects this perk your luck but its unknown how much, though people speculate -1 luck.
