[[błyskać]]
Fragment of a discussion from User talk:Kephir
It was part of an internet chat that I happened to see:
<person1> przekleństwo <person1> najpopularniejszy znak interpunkcyjny w Polsce <person1> >.> <person2> faktycznie popisałem się językiem... <person1> ... i kulturą :P <person2> linuxowiec? <person1> Windows * person1 błyska z oczu
Reads like bash.
I guess it means "[person2] gives a terrifying look", probably some allusion to the second definition I wrote, so more literally it would be "[person2] strikes a lightning from [their] eyes", but it is really hard to tell. Are you sure you got people's names right?
