A middle aged fatty always brags about his black Toyota Supra. He always claims that his car is slow by the quote "My car is slow bai" in order to get some other people to reply something like "No, your car is fast". This sentance actualy means "My car is slow, BYE" when smoking his rival. Because he overused this quote and then some other people have started making fun of him imitating him.
A: My car is slow bai.
B: So you drive a Supra
