A word meaning someone is of neither sexual preference, not Gay or Straight, they 'swing' both ways.
Prime example,...Sonia on Eastenders...she married martin, then 'fell' for her girl friend. She has pendulam pants, swinging between both gay and straight relationships! Hence a Pendulam, swings backwards and forwards.
