A girl you're aquainted with who when you go out together they never get hit on.
Usually ends up ignored for the night and is a major cockblocker when her friend is with a guy.
The hot friend will get complimented and hit on all night while the ugly friend is ignored. She will usually end up having to approach guys and then gets rejected ( most of the time).
Whenever we go out we always know sarah will never get hit on.
Don't bring her out, she's known as an ugly friend aka cockblocker extraordinare.
