I can’t think of a short-hand term for that certain type of negotiator who breathlessly swings at issues and treats every new redline clause as a personal affront, like the overbearing neighbor who chases a bee into the house and swings at it with a hammer, smashing all the fixtures and furniture until the room is a shambles and the bee is finally dead and who then smiles and wipes his brow and waits for congratulations from his adoring fans.
