Like [cuddling] and [spooning], when youre physically close to someone, but usually with your clothing on, both lying side-by-side in the same shape (like an S shape) and speaking without words. Might follow sex, maybe not. A comforting act mostly. It makes you feel happy.
When two people are hugging, one usually to comfort the other, and one has their face buried in the others shoulder. Will hold on until they feel better.
