英语 迷人的混蛋怎么说

"Charming scoundrel" is a phrase that could be used to describe a person who is attractive or charismatic but also dishonest or unreliable. It is a bit of a tongue-in-cheek way of describing someone who has a bit of a roguish or mischievous personality, but is still likable or appealing in some way.
For example, you might say: "He's such a charming scoundrel - I can't help but be drawn to him, even though I know he's trouble."
Note that this phrase is used somewhat tongue-in-cheek, and might not be taken entirely seriously. It is usually used in a playful or lighthearted way, rather than being a serious insult.
