1. A celebration in which little kids dress up and get stuff.
2. A series of movies where anyone who has sex dies.

It's when you dress up in either cheap, store-bought costumes or elaborate, self-made ones, watch Rocky Horror Picture Show, get your friends to do the Time Warp, and go on a severe candy binge. Until someone spoils your fun by reminding you that it's April.

An annual excuse for girls to dress like sluts and get away with it.

A holiday much like Spain's Day of the Dead. Everyone dresses up in costumes and little kids go around their neighboorhood trick-or-treating for candy. Pumpkins are carved and spooky decorations are set up.

One of the greatest holidays of all time. Children don disguises and travel to the houses of strangers to receive sugary goods by reciting the ancient enchantment "Trick or treat." Also an excellent night for teenage mishief.

All Hallow's Eve, the evening of October 31st.

Halloween was Christianity`s failed attempt at eradicating paganism in the 9th Century.
Originally, the pagans dedicated the period of late October to early November as a time for honoring their ancestors. Then along came the Christians, who declared November 1st to be All Saints Day and forced the pagans to honor that day instead. The pagans simply celebrated their ancient traditions in secret on the evening before November 1st.
When the Medieval Era ended, and the age of Protestantism began, the pagan tradition was celebrated more openly, eventually becoming an evening holiday in the Western Hemisphere.

October 31, celebrated in the United States, Canada, and the British Isles by children going door to door while wearing costumes and begging treats and playing pranks.
