A honeycutt is some one, normally a girl who is actually a total bitch, but she's usually polite and sugarcoats everything so that it sounds like she's not. Often a very social person, very attractive and manipulative. Most of the time she will never be directly rude to someone, but will make them feel inferior by being "Fake nice".
Although, this can be a bad or good thing for some girls - It would depend on the situations and people this approach is used with. Also, oftentimes the "honeycutt" won't consciously be thinking that they're treating people this way, it's just the way they are.
Instead of telling someone to fuck off, she'll make it sound sweet as sugar so the other person would feel rude if they didn't do as they were asked - Likewise if she wants a favour from someone, and it will also almost sound like she's doing them a favour.
