A Mat Rempit is a Malaysian term

A Mat Rempit is a Malaysian limit for an individual who participates in nefarious passage racing, usually involving underbone motorcycles (colloquially known as Kapcai) or scooters. Not all Mat Rempits are involved in street racing some of them accomplish crazy 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),or shuttu le katti. Mat Rempits usually operate in groups and race in bustling city centres on weekend nights.In recent times, Mat Rempits have been linked to gangsterism, gang robbery,12 street fighting, assault,3 vandalism, theft and bullying. some motorcycles used by the Mat Rempits do not meet standard specifications, or have been modified extensively for greater speed, or just to shoot the exhaust noisier. Additionally, some Mat Rempits do not have valid motorcycle licenses, do not pay road taxes, and ride stolen motorcycles. 45 A festering number of housing estates have also been turned into racing tracks. 6 It is estimated that there are about 200,000 Mat Rempits in Malaysia. 7 In some other countries, the term Mat Rempit is also used, but more to refer to one as a motorcycle lover or rider (Mat Motor), as opposed to an illegal motorcycle racer. Sometimes, the term Mat Rempit is misused to refer to any individual who rides an underbone motorcycle. Related to this is the Mat Konvoi, which claim to be the non-racing version of Mat Rempit.
