Question

Chill Out relax, calm down

Accepted Answer

When Chris threw down the paddle after he lost the Ping-Pong game, the counselor told him to chill out. When a person starts to get angry, we often use expressions like "steamed up" and "hot under the collar" to describe his or her emotions. If being heated up suggests being overly excited, then it's easy to see how the opposite means calm. "Chill out" is a recent African-American idiom, and so are other similar expressions like "take a chill pill" and "cool it."
