Tiu lei lo mo chao fa hei
Tiu kau lei ler
Lei gor sei ham kar chang
Gor tiu sor lo
Gor tiu lung tao
Tiu lei lo mo chao hei sei chao hei
Lei oi sei ah fai di ler
Tiu na sing
Lee gor hum gar ling
Gek to hoey choeng toy do bao 

And many expressions may not exactly be vulgar but are witty and sarcastic. If we quarrel with a honkie in Cantonese we will lose.

KNNBCCB lah!
