The personae of being blazed and chill. When you are twilked out then you are just in a state of mind that no one else could even hope to comprehend. A twilked out person usually wears nothing but shaggy, corduroy clothes and has a disheveled mass of hair giving off the look of a stoner or one who loves to blaze.
