Dingen is a Dutch word that can literally be translated as "Things" or "Stuff" - being the plural of the Dutch word "Ding" (thing).
Dingen can be used very effectively as a placeholder word for when you do not what to say, or forget the word that you wanted to say. Here, the versatility of Dingen presents itself - becoming a replacement for any word in existence.
Scenario 1:

Woman 1: "I kept the dingen on the dingen next to the other dingen"
Man 1: "Ahh of course, that definitely clarifies dingen"
