The line is attributed to Zdravko Mamic, the long-time Dinamo Zagreb football executive known in Croatia for blunt and controversial public outbursts. In the clip he addresses someone called Flak and says that seeing him gave him diarrhoea straight away. The phrase has circulated online as a short Croatian meme sound, shared mainly in football banter and Balkan comedy edits where an exaggerated disgusted reaction is the joke. Its staying power comes from Mamic's recognisable voice and the crude, quotable wording.
