What Does GC Mean?

The Quick Answer

GC most commonly means "Group Chat." However, it also has a number of other meanings, including "Good Condition," "Good Call," "Gay Couple," and "Garbage Collect."

Group Chat

Many instant messaging services, such as WhatsApp, have a chat feature that allows users to send a message to multiple contacts within a group. This is known as "group chat" (often abbreviated to GC). It is typically used by family groups, groups of friends, or clubs.

Sam: Let's make a group on WhatsApp and start a GC.
Ali: Great idea! But, I'm the only friend you've got.

Good Condition

GC is commonly seen on sites such as eBay and Gumtree, as well as in classified advertisements in newspapers, where it is used to indicate that an item offered for sale is in "good condition." For example:

Lee: How can they claim this is in GC? The fan doesn't work.
Jo: What is it?
Lee: A fan!

GC contrasts with the following terms, which indicate the sale item is in perfect condition:

BNIB - Brand New In Box.
BNWOT - Brand New Without Tags.
BNWT - Brand New With Tags.
LNIB - Like New In Box.
NIB - New In Box.

Good Call

In general online chat and in text messaging, GC means "good call" and expresses approval of a decision or suggestion. It is like giving a verbal (or typed) thumbs up. For example:

Jordan: I'm not drinking tonight. Need to be on the ball for the exam tomorrow.
Jay: GC! I'll join you.

In computing, GC is with the meaning "garbage collect" (or "garbage collection").

Until the early 2000s, the process of GC was something programmers had to do with code during runtime. However, it is now generally an automatic procedure.
