An agitator is a person who actively supports some ideology or movement with speeches and especially actions. The Agitators were a political movement as well as elected representatives of soldiers, including the New Model Army of Oliver Cromwell, during the English Civil War. They were also known as adjutators. Many of the ideas of the movement were later adopted by the Levellers.
Agitators, or adjutators, was the name given to representatives elected in 1647 by the different regiments of the English Parliamentary army. The word really means an agent, but it was confused with "adjutant," often called "agitant," a title familiar to the soldiers, and thus the form "adjutator" came into use.
Early in 1647 the Long Parliament wished either to disband many of the regiments or to send them to Ireland. The soldiers, whose pay was largely in arrears, refused to accept either alternative, and eight of the cavalry regiments elected agitators, called at first commissioners, who laid their grievances before the three generals, and whose letter was read in the House of Commons on the 30 April 1647. The other regiments followed the example of the cavalry (nicknamed Ironsides), and the agitators, who belonged to the lower ranks of the army, were supported by many of the officers, who showed their sympathy by signing 'Declaration of the army.
A pest in ice hockey is a player who attempts to antagonize opponent players either by physical play or verbal incitation. Pests employ legal, illegal, or borderline tactics to accomplish their goals. Some common tactics include trash talk or slashing and hooking while referees are not looking. They may employ the tactic of goading opponents into a fight but then backing off in order to draw a penalty against them. Some pests may not only use these tactics against opposing skaters, but opposing goaltenders as well. Pest and agitator are sometimes used synonymously, as both are usually characterized by short bursts of intensity and speed with the intention of creating havoc. The pest characterization has been used derogatorily, as a player who incites anger in the opposition but is unwilling to directly confront the result of their actions by engaging in fighting, as would an enforcer. George McPhee, former general manager of the Washington Capitals, said, "Pests are really the guys who have no courage. They start stuff and don't back it up."
