conversational manspreading

When someone completely dominates a conversation, especially in a meeting, making all the possible salient points anyone else could possibly have made, then when anyone else tries to add a point, partially or completely dismisses their ideas.

Our retro was 100% the Rob show, conversational manspreading the first 20 minutes. When I finally could talk I said we need a security breach process. He interrupted me and said, "well I'm not concerned about that right now. Anyway it's not necessary."
