What word did Dahl use to describe children around adults?

Roald Dahl famously used the word "gloop" to describe children in the presence of adults. He used it in his book "Charlie and the Chocolate Factory," where Willy Wonka describes the children as "a gloop of kids."

He also used the word "gloop" in other books like "The Witches" and "Matilda." It's a playful and somewhat derogatory term that reflects his view of children as being somewhat sticky, messy, and chaotic when in a group.
