“脚踏两只船”，中文俗语，字面意思是“have one’s feet in two boats”，比喻跟不同阵营的两方面都保持关系（to be connected to two groups with opposing interests），可翻译为“have a foot in both camps”。
如今，“脚踏两只船”一般用来形容玩弄他人感情、同时维持多段恋爱关系（have more than one romantic relationship at a time）的行为，含有贬义，与英文“two-time”意思相近，表示“deceive or be unfaithful to (a lover or spouse)”。
- 当我发现他脚踏两只船后，就和他分手了。
I ended the relationship when I found out he was two-timing me. - 你确定他没有脚踏两只船？
Are you sure he is not two-timing you?
