Trick 'r Treat

Trick-or-treating is a traditional Halloween custom for children and adults in some countries. During the evening of Halloween, on October 31, people in costumes travel from house to house, asking for treats with the phrase "trick or treat". The "treat" is some form of confectionery, usually candy, although in some cultures money is given instead. The "trick" refers to a threat, usually idle, to perform mischief on the resident(s) or their property if no treat is given

jack-o'-lantern

jack-o'-lantern (or jack o'lantern) is a carved vegetable lantern, most commonly made from a pumpkin or a root vegetable such as a turnip. Its name comes from the reported phenomenon of strange lights flickering over peat bogs, called will-o'-the-wisps or jack-o'-lanterns. The name is also tied to the Irish legend of Stingy Jack, a drunkard who bargains with Satan and is doomed to roam the Earth with only a hollowed turnip to light his way.

Dressing up in costumes and going "guising" was prevalent in Scotland and Ireland at Halloween by the late 19th century. A Scottish term, the tradition is called "guising" because of the disguises or costumes worn by the children. In Ireland and Scotland, the masks are known as 'false faces’, a term recorded in Ayr, Scotland in 1890 by a Scot describing guisers: "I had mind it was Halloween . . . the wee callans were at it already, rinning aboot wi’ their fause-faces (false faces) on and their bits o’ turnip lanthrons (lanterns) in their haun (hand)".
