Etymology: from English dialectal kipper (nimble, frisky), of obscure origin.
Adj. 1. Exhibiting a lively optimism; in high spirits; cheerful. E.g. she was very chipper after making the quick find on the D5 geocache.
Noun. 1. A machine that reduces organic matter to compost; depending on size, whole tree trunks are reduced to sawdust. E.g. the well-hidden geocache met an early demise when the city crew came through the park with a chipper.
2. (Ireland, Scotland, slang) A fish and chip shop, or more generally a cheap fast-food outlet, typically selling chips and other deep-fried foods. E.g. after a long day of geocaching, the hardy crew visited the chipper for a well-deserved feast.
3. (golf) A golf club for making chip shots. E.g. when looking for a TOTT for a T3 hide, the cacher found a chipper in his trunk.
The cache is not at the posted coordinates, in fact it might be a fairly dangerous place to venture to. Instead you have to visit this chipper.
