CC

In MMORPGs, MOBAs, and other online games, CC stands for "crowd control." If another player asks you for CC, it means they want you to stun or immobilize an enemy (or group of enemies).

There are a number of ways a player might perform CC within an online game. For example, many player characters (PCs) can stun, trap, knock back, blind, or otherwise disrupt enemies. If a CC effect completely neutralizes an enemy, rendering them unable to fight, it is called hard crowd control. If a CC effect impairs an enemy but leaves them able to fight, it is called soft crowd control.

CC means carbon copy. It is an email field that allows the sender to copy a message to one or more other addresses besides the main recipient.

While CC is commonly used as a noun it can also be used as a verb, i.e. "CC the rest of the group in your e-mail as well." It appears above the "BCC" field and below the "To" field at the top of an email.

An acronym for the primary building in a Terran player's base in the multiplayer game StarCraft.

A payment card offered by companies such as Visa, American Express, and MasterCard.

Some online chat users use CC to stand for "I copy," which is another way of saying "I understand." This version of CC is used in response to requests or assertions, to let you know you've been heard and understood.

Typically, users who are using CC to mean "I copy" place the acronym at the beginning of their messages. While this usage of CC is uncommon, you may still encounter it while chatting with older users.
