Twist-out
Defined curls made by twisting damp hair, letting it dry and then unwinding the twists.
Also: braid-out (related)
A twist-out sets the curl pattern of natural hair with two-strand twists. The hair is twisted damp, often with a cream or butter, and left to dry fully, sometimes overnight. The twists are then unwound and gently separated, leaving defined, stretched curls with less shrinkage. Bigger twists give looser curls. It can be refreshed for several days and is one of the most common looks in the natural hair movement.
