what is a kvasar
But it looks like that the Scandinavian and the Slavic languages use the form "kvasar".
https://en.wiktionary.org/wiki/kvasar
According to that entry, it appears in both Swedish and Czech (as an alternate spelling).
Given the commenter's username is krokku and the fact that "krok ku" means "(a) step forward/towards" in Czech, I think we can assume that the commenter is Czech.
Or go directly to Wikidata https://www.wikidata.org/wiki/Q83373
But with the additional clue from the username I'm still betting on Czech.
(I hear "kvasar" and "cantoom" for quasar and quantum)
Stop being kvazy!
