Please just explain what Germany is saying to France in the meme?
Germany is ending the word “cousin” with the same sound as English “boing”. There is no simpler explanation, and don’t pretend like it depends on knowing IPA. Understanding depends on knowing how “cousin” and “boing” are pronounced correctly.
If you cannot understand it from this, if you can’t hear how those two sounds differ, then I can’t help you. Maybe listen to some audio files of those nasals until you can tell the difference.
