a Slasher is a millennial term that refers to a person of any age that adopts a frame of mind that revolves around personal success, personal fulfillment, and financial gains. They are limitless and don’t like settling for one job or career path. They pursue their life’s biggest passions and make money doing so. Most slashers are either active or dormant entrepreneurs that understand the importance of maximizing their time by filling their lives with experiences that bring them a great deal of satisfaction and joy. Slashers come from all walks of life, and are also referred to as “hustlers”/ “work-a-holics”. Although it is not a requirement for slashers to be work-a-holics , they are prone to work endlessly in pursuit of accomplishing their goals because of their thirst and hunger for success &/or personal fulfillment. Like the name suggests they go through life slashing their way through their dreams and goals.
