The phrase comes from EAV, the Austrian band behind Einer geht um die Welt, where it is delivered as a short sung line. In everyday German, es hat mich sehr gefreut is a standard polite expression meaning it was a pleasure, which makes the clip instantly recognisable even outside the song. Lifted as a four-second sound, it works independently of its original context and has found a second life in short videos and soundboards, where creators use its formal tone for comic contrast. Its appeal endures because the politeness feels both sincere and slightly theatrical.
