No this doesn't mean telling it upsetting news, distressing is the furniture makers term for making something new, look old.
You do this by mixing up a wash of black. NOT too washy, but enough so that it remains wet long enough to be able to wipe it off. The best type of paint for this is acrylic. DO NOT paint the whole wand before starting to wipe the paint off otherwise it will dry and you won't be able to wipe it off.
