A Mat Rempit is a Malaysian term for "an individual who participates in immoral activities and public disturbance with a motorcycle as their main transport", usually involving underbone motorcycles,^[1] colloquially known as Kapcai, or scooters. Mat Rempits are not involved in street racing but rather go against each other for cheap thrills and to rebel against authorities while some of them perform stunts for fun, such as the wheelie, superman (lying flat on the seat), wikang, and scorpion (standing on the seat with one leg during a wheelie).
