To shake up, agitate, or disturb greatly; to shake out or scatter vigorously.
From Latin exagitatus, combining ex- (out, intensively) and agitatus (agitated, from agitare meaning 'to shake'). The word developed to describe vigorous shaking or disturbance.
The root agitare literally means 'to shake'—the same root appears in 'agitate,' 'agent,' and even 'navigate' (ships navigating through rough waters)—so exagitate is intense shaking that sends things flying out.
