The word "豁出去" is formed by combining the verb 豁, which conveys "to risk" or "to break open", with the sequential directional complements 出 ("out") and 去 ("go"). This structure places 豁 as the core action, followed by 出去 to indicate the direction or completion of the action, literally suggesting "to risk going out", which idiomaticaly means to act without holding back or to throw caution to the wind.
