Trunk or treat is a Halloween event where children collect candy from decorated car trunks instead of walking from house to house.
The phrase combines “trunk,” meaning the rear storage area of a car, with “treat,” referring to the candy given to children.
People sometimes wonder whether it should be written as “trunk or treat,” “trunk-or-treat,” or “trunk or treating” because the term is fairly modern and used in different ways.
This guide explains the correct spelling, meaning, origin, and common uses of trunk or treat.
You will also learn how the phrase works in American and British English and how to use it correctly in writing.
Quick Answer
Trunk or treat is a Halloween activity in which children go from car to car to receive candy. Instead of visiting individual homes, families meet in a parking lot, school, church, community center, or similar location.
Adults decorate the trunks of their cars with Halloween themes. Children then walk from vehicle to vehicle and say “trick or treat” while receiving sweets.
Example
Our school is hosting a trunk or treat event on Friday night.
The standard form of the phrase is trunk or treat when it is used as the name of the event.
You may also see trunk-or-treat in some writing, especially when the phrase is used as a compound modifier. However, trunk or treat is the most common general form.
The Origin of Trunk or Treat
The phrase trunk or treat comes from the traditional Halloween practice of trick-or-treating.
The older tradition involves children walking from house to house and asking for candy. Trunk or treat changes the location from residential streets to a group of decorated vehicles.
The word trunk refers to the enclosed storage compartment at the back of many American cars. In British English, this part of a car is usually called the boot.
The word treat refers to something enjoyable given to someone. In this context, it usually means Halloween candy, sweets, or small prizes.
The exact beginning of trunk or treat is difficult to identify because the activity developed through local communities rather than from one single creator. It became more common in the United States as schools, churches, neighborhoods, and community groups began organizing controlled Halloween events.
The format can make Halloween easier to organize because children remain in one area rather than traveling between many houses. It can also provide a social event where families decorate cars, play games, and share food.
Why Is It Called Trunk or Treat?
The name is a play on trick or treat.
Instead of:
House → House → House
children visit:
Trunk → Trunk → Trunk
The phrase therefore describes both the activity and its connection to traditional Halloween trick-or-treating.
British English vs American English Spelling
There is no major American-versus-British spelling difference for the phrase trunk or treat itself.
The important difference is the word trunk.
In American English, the rear storage area of a car is called the trunk. In British English, it is usually called the boot.
This means that trunk or treat is strongly associated with American English and American Halloween culture.
| Meaning | American English | British English |
|---|---|---|
| Rear storage area of a car | trunk | boot |
| Halloween activity | trunk or treat | No widely established equivalent |
| Traditional Halloween activity | trick-or-treating | trick-or-treating |
| Candy | candy | sweets |
| Common event wording | trunk or treat event | Halloween event / trick-or-treat event |
A British speaker would understand trunk or treat, especially when discussing American culture, but the phrase may sound distinctly American.
Trunk or Treat vs Trunk-or-Treat
Both forms can appear in writing:
- trunk or treat — common when naming the activity
- trunk-or-treat — sometimes used when the phrase acts as a compound adjective
For example:
We are going to a trunk or treat tonight.
The school organized a trunk-or-treat event.
For most general writing, trunk or treat is the safest and clearest form.
Which Spelling Should You Use?
Your choice depends mainly on your audience.
For American English
Use trunk or treat when referring to the Halloween event.
Examples:
The church is hosting a trunk or treat.
Bring your children to our annual trunk or treat.
We need volunteers for the trunk or treat event.
For British English
If your audience is in the UK, you can still use trunk or treat when referring to the American event. Do not change “trunk” to “boot” unless you are deliberately explaining the difference.
For example:
The American community group held a trunk or treat event.
Calling it boot or treat would not normally be the standard name of the event.
For a Global Audience
Use trunk or treat and explain it briefly if readers may not know the term.
For example:
Trunk or treat is a Halloween event where children collect candy from decorated car trunks.
This makes the meaning clear without assuming that every reader knows the American term.
Common Mistakes with Trunk or Treat
Because the phrase is relatively modern, several variations appear online.
1. Writing “Trunk and Treat”
Incorrect or less common: trunk and treat
Preferred: trunk or treat
The phrase intentionally follows the pattern of trick or treat.
2. Writing “Trunk-or-Treat” Everywhere
Less natural: We went to a trunk-or-treat.
Preferred: We went to a trunk or treat.
Hyphens can be useful when the phrase modifies another noun:
a trunk-or-treat event
But they are not necessary every time.
3. Writing “Trunk Treat”
Some people shorten the phrase to trunk treat.
This may be understood, but it removes the connection to the familiar phrase trick or treat. Trunk or treat is clearer.
4. Confusing Trunk With Boot
American English uses trunk for the rear storage area of a car.
British English usually uses boot.
Therefore:
trunk or treat = American term
It is not normally changed to “boot or treat” in British English.
5. Using “Trunk or Treating” Incorrectly
The noun phrase is trunk or treat.
When describing the activity, trunk-or-treating may be used informally.
Example:
The children went trunk-or-treating after dinner.
For an event name, however, trunk or treat is usually clearer.
