Relaxing or hanging out in a calm and laid-back manner. Often used to describe a state of being at ease, doing nothing stressful or important.

Derived from the English word "chill," meaning to relax or cool down. The informal version, chillin', drops the final "g" in typical casual speech and has become a widely used term in slang, including in Puerto Rican English, to describe hanging out or relaxing.
