Lighter dudes

A person holds a lighter with a large flame, then uses it to ignite a small object on their wrist, causing a brief burst of fire. The scene shifts to another person in a grey sweatshirt and white sandals, who then uses a lighter to ignite a small object on their wrist, producing a flame. The sequence ends with a person in a black outfit standing behind a table, holding a device with a flame, and smoking a cigarette. The setting appears to be an indoor space with a concrete floor.
