Glokaya kuzdra (Russian: Глокая куздра) is a reference to a meaningless but grammatically correct Russian language phrase, similar to the English language phrases using the pseudoword "gostak". It was suggested by Russian linguist Lev Shcherba. The full phrase is: "Гло́кая ку́здра ште́ко будлану́ла бо́кра и кудря́чит бокрёнка"

 

This is a little linguistic joke.
