From Crackle:
We are expatriates living in Malaysia, and are bothered by Mak Rempit (illegal motorcyle racing in English) almost every mid-night of Friday and Saturday. Here Minah rempit
is just one case of the notorious Malaysian illegal motorcyle stunts on the major countryside or city roads. Those Malay guys are much more crazy than you can believe!
p.s., If you are a new expatriate living or to live in Malaysia, don't walk alone along the major roads in Kuala Lumpur, Klang, Johor Bahru and Penang among others after 24:00 every Friday and Saturday. Otherwise, you will definitely be in a dangerous situation if you run across those Mak Rempit drivers. No cheating!
