History of origins of halloween
The ancient Gauls or Celts were the first to have celebrated a day identified as Samhain. It is believed that the name of the holiday is derived from the word Samonios; it was the beginning of a New Year for the Celts. The ancient Gaulish people did not celebrate four seasons, but two, each representing the light or dark half of the year; rightly so, Samhain fell during the time marked by darkness and became a holiday associated with the diminishment of light, darkness, and death. Since the season grew colder and plants began to die off during this time, Samhain marked the early entrance into the wintry season and easily became associated with death and the deceased. In ancient times, Samonios or Samhain was a three day celebration marked with customs that paid respect to deceased ancestors and involved giving thanks to the harvest one received from the spring and summer seasons.
Trick or treat; smell my feet; give me something good to eat.
Trick or treat; smell my feet; give me something good to eat. If you don't, I don't care. I'll pull down your underwear.
Happy Halloween! - this is the expression used for wishing someone a happy Halloween night
Trick of Treat! - this is the greeting that kids announce when they go around from door to door looking for candy in their costumes
Additionally, there is a very long rhyme that some kids repeat when they knock on the different doors. It goes like this:
"Trick or treat, smell my feet give me something good to eat. If you don't, I don't care. I'll pull down your underwear."
Basically, it's saying if you don't give me a candy I like, then I will prank you or trick you by pulling down your underwear.
Happy Halloween! -ハッピーハロウィン
ハロウィンの夜が楽しくなるように願う時に使われる表現です。
Trick of Treat! - トリックオブトリート
子供たちが、衣装を着て、キャンディをもらいに家をまわる時に、子供が言う挨拶です。
さらに子供が他の家のドアをノックする時に、子供が繰り返して言う長い韻を踏んだ表現があります。このような感じです。

A different expression usually used other than "Trick or Treat" on Halloween is "Happy Halloween".
