许多人都be scared of rats，想来和老鼠相关的都不该是好词。Love-rat，爱情老鼠，听起来也是全身不舒服。

的确，Love rats are terrible. They're people who cheat on their partners, and they're quite often men. Love-rat 爱情老鼠的真正意思就是爱情骗子，指那些经常在恋人背后出轨的人。

例句： I've met people who just can't stop cheating on their partners. They're love-rats and they're getting away with it.

对话： A: Have you read the story on Britain's biggest love-rat in the papers this morning?

B: No, not yet. What did it say?

A: Well, apparently Britain's biggest love-rat has 12 children with 12 different women, all of whom he has cheated on at least five times.

B: That's disgraceful. He shouldn't be getting away with it.

We also hear the expression love-rat used quite often in popular newspapers. 爱情老鼠这个表达也经常出现在那些通俗小报上。

Have you ever met someone who's a love-rat? 你遇到过爱情骗子吗？

过街老鼠，人人喊打。爱情老鼠，也该人人喊打！
