[3] túsi (m.) ‘crackling one’: Or tusi (the quantity of the vowel cannot be established with certainty). A hap. leg. Cf. New Norw. tusa, tuska ‘crackle, make noise’ (see AEW: tusi). Kock (NN §105 n.) argues that the correct form of this heiti is tussi, and that it may be related to tjǫss ‘whistling’ (hence ‘noisy’). Alternatively, the word could be related to OHG zusken ‘burn’ (so Holthausen 1942, 270).
