knocking wood

Touching tree material

Knocking wood is the superstitious practice of rapping one's knuckles on something wooden after mentioning good fortune, to ward off bad luck: I haven't been sick all year, knock on wood.

The gesture acknowledges that fate might punish boasting.

Often the speaker knocks on the nearest wooden surface—a table, doorframe, or their own head if nothing else is available.
