Communication styles are cataloged in many ways, but the CSI (Communication Styles Inventory) distinguishes six of them, one of which is the expressive style.
People with this style can be recognized by the fact that they often and easily take the initiative in conversation, they talk a lot, suggest the topic of conversation, have a sense of humor and do not hesitate to use it for their own purposes. They address everyone around them in an informal way, quickly breaking the ice.
