I think the Wingding that baran referred to is a "Massacre festivities" ...wingding is also used as a slang words which is referring to an event or festivity or a party...
Despite of what the baran did to the all monsters (means killing the monsters which is then become the shadows soldier),and when the monarch king ask him why he did all those things and betray him,he just said "wingding" which referring to a festivity things that been happened,like addicted to killing all the monster for the higher status than the monarch king.
That's what my opinion is. 😬😬
