Question: If I wish to eat some of the chocolate my friend is eating. Can I say:

> 
> 1. Give me a bite.
> 2. Share me a bite.
> 3. Let me take a bite.
> 4. Can you share a bite?
> 
> 
> 

**Important: Does it have any taboos meaning too?**

Answer: 
Firstly, it’s “than”, not “then”.

As Kate Bunting mentions, the second example is valid, though rather old-fashioned and formal.

The first sort of sounds like it’s trying to say:

> 
> Men are rather impressed by beauty.
> 
> 
> 

“Rather” here just means “very”.

One acceptable and common way to phrase what you're trying to say would be:

> 
> Men are impressed by beauty rather than (by) character.
> 
> 
> 

Also note that the second “by”, which I’ve bracketed, is optional.
> 
> Men are rather impressed by beauty than character.
> 
> 
> 

Will rather be the right answer to your question.

Here `rather` is giving more emphasis on one over the other.
