friendcestuous 

Like incestuous, but with your friends. A group of friends that's oddly, freakishly close with each other. Hold hands, occasionally kiss, share toothbrushes. Sometimes significant others of the friends get jealous of how touchy feely they are.

Those girls over there are so friendcestuous. It's kinda hot, actually. They keep cuddling and licking each other.
