As a language expert with a deep understanding of idiomatic expressions, I can explain that the phrase "I want to eat you up" is not meant to be taken literally. It is an idiomatic expression that is often used to convey a strong feeling of affection or admiration towards someone, typically in a playful or endearing manner. It suggests that the speaker is so fond of the person that they could metaphorically "consume" them with their affection.

When someone says "I want to eat you up," they are usually expressing that they find the person incredibly attractive or delightful, and they want to be close to them or show them a lot of love. It's important to note that the context and the relationship between the two people involved will determine the appropriateness of using this phrase.
