Skálda-spillir

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

skálda-spillir

m. ‘skald-spoiler,’ the nickname of the poet Eyvind; the name was, we believe, a bye-word, a ‘poetaster,’ ‘plagiarist;’ we believe that this nickname was given to this poet because two of his chief poems were modelled after other works of contemporary poets, the Háleygja-tal after the Ynglinga-tal, and the Hákonar-mál after the Eiríks-mál; (as to the latter poem this is even expressly stated in Fagrsk. 22); the word would thus be the same as íll-skælda, a word applied to a poet for having borrowed the refrain of his poem, Fms. iii. 65.
