“脚踏两只船”，中文俗话，字面意思是“have one’s feet in two boats”，比方跟不同阵营的两方面都坚持联系（to be connected to two groups with opposing interests），可翻译为“have a foot in both camps”。

现在，“脚踏两只船”一般用来描述戏弄别人爱情、一起保持多段爱情联系（have more than one romantic relationship at a time）的行为，含有贬义，与英语“two-time”意思附近，表明“deceive or be unfaithful to (a lover or spouse)”。

例句：

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.

你确认他没有脚踏两只船？

Are you sure he is not two-timing you?
