Most often refers to the act of smoking marijuana while driving. Common location is generally an unpopulated area or backcountry road. In reality, a TRUE burn cruise consists of leaving and returning to the original location without stopping; the sole purpose of using the car is as a smoking venue. Length of drive may vary from a few minutes to a few hours depending on fuel efficiency and the ability to acquire a friends/parents gas card.
Person A: What are you doing tonight?
Person B: Hopefully smoking marijuana.
Person A: That sounds delightful. I will pick you up in 10 min and we'll burn cruise it.
