"Been Chow Chow" (BCC)

"Been Chow Chow" or "BCC" (not your email's blind carbon copy where you can literally hide the recipient list) in Singapore is usually used in reference to someone who is most probably displeased with something that someone else said to him or her.

The abbreviation "BCC" is often used on a person who exhibits these undesirable moody traits on their faces. For example, we say someone is "been chow chow" when they pull a long face. "Been" here to refers to "face" and is in Hokkien language which is quite commonly used in Singapore. "Chow" here means "Smelly". So in this instance, it means "Smelly Smelly".

The person that shows their outright unhappiness or displeasure, is usually the one that is referred to as "Been Chow Chow". 

So typically when someone is unhappy with words spoken about them, usually in a gossipy manner or  if they weren't invited to a common occasion where everyone else is invited, they will exude the facial expression that leads others to conclude that they are showing their unhappiness. Compare this to "Been Orh Orh" (BOO) which refers to a person with an extremely unhappy face.

A typical scenario to describe this would be as follows:

Person A: "Hey Person B, we are going for lunch, wanna join us?"

Person B: "Yeah, sure!"

Person C: "Can I join in too?"

Person A: "Oh, it's a private gathering, I'm sure you understand that. Maybe next time."

In this scenario, Person C would suddenly exhibit the exact signs and symptoms of being BCC or "Been Chow Chow" (lit: Face Smelly Smelly).
