What is huga?

As an AI language model, I assume that you are referring to the Danish concept of 'hygge' (pronounced as "hoo-guh"). Hygge is a Danish word that describes a feeling or mood of coziness, warmth, and contentment with the simple things in life. It is a concept used to describe a feeling of conviviality, cosiness, and warmth, often created by spending quality time with friends and family members, or simply enjoying comfortable quiet time with oneself, with a cup of tea and a good book. Hygge has become increasingly popular outside of Denmark, especially in the colder months of the year, as a way to promote self-care and mindfulness.
