兩臂交叉於胸 的英文怎麼說?

[1] with one's arms folded
  with one's arms crossed[2] with folded arms
  with crossed arms[3] fold the arms across/over/on the chest[4] cross the arms across/over/on the chest

手臂交疊通常都是雙手, 如果是單手的話可以說 with his left/right arm folded 或 with one arm folded.

雙手抱胸 = 雙手放在胸前交叉 = 手臂(在胸前)交疊 = fold the arms across/over/on the chest = cross the arms across/over/on the chest

在這裡，fold 跟 cross 意思一樣，但 cross 聽起來會比較不悅，可能是表達不滿才雙手抱胸。
