“I like a guy with a nice body, but if he's a little overweight I can live with it.”
You're talking with your friend and discussing what kind of guys you would like to date. A guy's weight isn't really important to you, so you say:
I like a guy with a nice body, but if he's a little overweight I can live with it.
You can use "I like a ___" to talk about things that you like sometimes. This phrase gives the impression of liking something a little bit, but also liking other things as well.
Notice that the example above doesn't mean that she likes one specific guy with a nice body, but that she usually or sometimes likes guys with nice bodies. Here are some other examples:
Sure, I like a nice glass of red wine with dinner from time to time.
I like a woman who's independent and knows what she wants in life.
Use the word "nice" to describe a person's body when they are slim, athletic-looking, and attractive. But, of course, don't go around saying this to people who you think are attractive. You'll probably get in trouble. It's better to use it to talk about people, especially models and celebrities.
"Overweight" means "fat". But it doesn't sound as bad as "fat" or "obese". So you use this word when you're describing someone who's only a little bit fat, or when you're trying to speak politely about a fat person.
It's common to use words like "a little" and "slightly" with "overweight" to make it sound even less negative.
Say "I can live with it" to talk about a situation that you don't like very much, but you are able to accept it. For example:
A: What do you think of the color?
B: Eh, I can live with it.
Use this in questions as well:
I think we've all decided to eat at Alfredo's. Can you live with that?
