Definition: Huff (adj.) The sound of a chair back padding poofing out air after a person eats an Easter feast and finally leans back to take a rest.
Eg. The truth of the matter is that she was so stressed by the time they got to Grandmas, that in the night, she secretly downed a goodly part of one of the cartons of marshmallow eggs. A couple of days later, while sitting next to her exhausted and pregnant cousin, she felt fine about the Hufffff of the chair after delighting in each bite of the home-made biscuit. No exchange of words needed.
