Never use profanity.

“Eh, shit lah kereta depan ni…”

“Memang shit lah perangai dia ni. Stupid!”

“Shit betul!”

Okay, after this, I will never use profanity.

I promise!

How about using “Shoot” or “Shucks”?

“Eh, shoot lah kereta depan ni…”

“Memang shucks lah perangai dia ni. Shoot!”

“Shoot betul!”

Sound better?

Err, maybe not!
