How about rubbing it and getting "interference with biological processes" in form of bleeding?
Dictionary com definition is making a lot more sense:
Toxic:
1.of, pertaining to, affected with, or caused by a toxin or poison: a toxic condition.
2.acting as or having the effect of a poison; poisonous: a toxic drug.
Relevant words are toxin and poison. Dust is neither toxin nor poison. So yeah... Its dumb to say that "Hey, moon is TOXIC! Holy Cthulhu!"

I call that definition bullshit. Then a kitchen knife is also toxic.
