[All]: The concept of a being that pollutes springs or streams by urinating in them is attested in Scandinavian folklore (cf. CVC: brunn-migi). It is sometimes imagined as a fox spirit, although here the being is called þuss ‘giant’ or ‘troll’. The cpd brunnmigi ‘spring-pisser’ appears only in the prose preceding this stanza and in Þul Grýlu 1/8III, where most of the other heiti in the stanza are terms for foxes.
