This is what makes the Mat Rempit brave or daring in their stunts.
They imbibe a mandatory special concoction prior to a race. It's made of tuak (fermented coconut or nipah sap) mixed with terrapin (little turtle's) blood. After drinking the alcoholic reptilian mixture, the Mat Rempits become daring enough to perform their death defying stunts, or alternatively kill some unsuspecting member of the public in the process.
Drinking the secret stuff is not an option - as mentioned, it's a mandatory ritual for the rider. I wonder whether they cry out yamseng or Malaysia Boleh when they tip the concoction over?
The daily Kosmo! discovered this Mat Rempit secret from one of the bikkies who revealed that the concoction gave them a different feeling of being high. He said: “Even if there is a narrow road, it will appear very wide to us.”
The terrapin blood is said to enhance the effects of the alcohol while the drink functions as a sort of ‘viagra’ to give the drinker the 'gnarng' (or 'gnair' = hard-on) to overcome fear. The confessor also revealed that there are a few places in Pasir Mas and Jeli in Kelantan that processed the drink secretly for Mat Rempit. The brew is sold at RM5 per packet or by weight.
I wonder whether there is budu in the Rempit-ish drink? But with the potent brew of tuak, terrapin blood and a drop or two of budu, I wouldn't be surprised at all if those Rempits could become cemerlang.
