“Co za asy” is a Polish phrase and video comment posted by YouTube user MrMal on a FAILblog video and later popularized through a webisode by YouTube personality Ray William Johnson. The phrase is roughly translated into “What an ace…” in English, though in the context of FAILblog video, it is likely the comment was written in sarcasm.
Because the phrase "co za asy" is so fun ( and catchy) to say it is being commented on almost every video that has to do with the Polish.
