〝大砲〞 英文怎麼說？

請問如何用最貼切的英文形容某人是〝大砲〞或〝大砲性格〞？ 謝謝指教！ adj outspoken [autˈspoukən] saying exactly what one thinks She's a very outspoken person Outspoken adj.1. Spoken without reserve; candid.誠實,坦白,不保留的表白2.

- 算得上〝大砲〞或〝大砲性格〞嗎？

he is a loose cannon.

絕對不可能是cannon

恩 outspoken應該比較接近原意，若翻成中文，
outspoken我會翻成「直言不諱」。

cannon 大砲 (N)

大砲:Cannon
大砲性格:Cannon disposition

straight ==> not gay.

straight。
例如，He is so straight. 他這麼直爽。(他這麼有「大砲性格」)

不知道什麼是〝大砲〞〝大砲性格〞所以沒辦法回答= =
