Little is documented about where Crec Crec first came from, and the name itself is simply the written form of the noise it makes, two short creaks in quick succession. Short onomatopoeic effects like this spread on soundboards because they are easy to search, preview and drop into an edit without any setup. The clip stays useful because the meaning is instant, even with no picture, and it pairs naturally with other dry effects like a bone crack in slapstick scenes about stiff joints and old furniture.
