Something unattractive or ugly at first glance or something that makes a first impression very unpleasant to the eyes; but also the more you look at it or get to know it the uglier it truly gets on the outside and also on the inside. Maybe even more so on the inside.
To put it simply Amie.
Yes the half brown "beans" Amie who can sing dance or act to save it's life, born in November of 2006 in Colorado.
That taint is the most unprepossessing thing I've ever encountered!
Some bitch born in November of 2006 called Amie
Friend: What do you call someone who is really, and I mean REALLY ugly?
Me: Ugly on the outside or inside, like their personality or something?
Friend: Both actually.
Me: "Fugly." Or you could call them "Amie" for the sake of simplicity.
