if you dont get a treat you do a trick on the one that didnt give you a treat
Trick or treat!
Children trick-or-treat more than adults. Most towns won't even let people in high school (or older) trick-or-treat.
Most of the time, people like to trick-or-treat from about 8:00 P.M. to about 10:00 P.M.
Trick or treat!
to scare the crap outta people
Before people said 'Trick or Treat', since Hallowe'en is a Celtic Celebration, they said calaverita, Which means 'Little Skull'.
If you did not hav a trick they will NOT giv you candy.
No, it isn't one word, but is acceptable as either trick or treat or trick-or-treat.
The real question is when was trick taken out. The word trick of trick or treat has always been there but when people got more used to handing out candy and everyone got a piece then people forgot to say trick and kids would be unprepared for the few that did. Really now people should say Treat!
the phrase trick or treat has an American origin because on Halloween people often give candy (treats) or lay pranks on each other (trick).
Sometimes they give candy or even money. But when no 'treats' are given, then the trick comes.
