Touch wood is said to avoid spoiling your own luck by mentioning it. You say something is going well, and then you say this.
It is one of the few superstitions almost everybody performs without believing in, and many people actually reach for a table while saying it. Americans say knock on wood. The origin is genuinely unknown, with theories about tree spirits and about the wood of the cross, none of them provable. The phrase usually comes at the end of a sentence.
