Corrupted (Fallout 2)

You apparently had a chance encounter with a bad dog near a pile of corpses, so it gives you this ability.

Yes, I know about trait, but it's an ability, not a trait.

Since "Corrupted" is displayed in your abilities, and not in features (which are set during character creation), the only option, as it was said by the user LENNH, you met a so-called bad dog. For a meeting with her, it is precisely the ability with the exact same name and the same effect as the corresponding trait is given.

OK got it. Here is a bad dog. And I really thought there was some kind of bug.
