The ugly girl will usually have a history of being unwanted- both by family and men/boys in general.
Will usually be used as a fuck and chuck, if that.
Due to this low value she will lash out, whether on the internet or towards another girl.
The ugly girl has a history of being known as " the unnatractive one" or the one who can't keep a man's interest other than for one night of sex.
Will usually end up pregnant and abandoned multiple times and die alone.
