The phrase “she’s a 10 but…” is a popular internet meme that is used to describe someone who is physically attractive but has a flaw or negative trait. The “questions” in the phrase refer to the unknown or unspoken flaws that the person may have. For example, someone might say “she’s a 10 but she’s always late” or “she’s a 10 but she’s really bad at cooking.”
The phrase is often used in a humorous way, but it can also be used to point out real flaws in a person’s character or behavior. In some cases, the “questions” can be serious red flags that indicate that a person is not a good match for a relationship.
