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.
