A girl who is very attractive but due to more attractive sister(s) or long term friends has not gotten exposed to people thinking she's hot since they all go for the sister or friend. Usually consider themselves ugly and like in Ugly Duckling Syndrome have good personalities and will date any guy because "Looks aren't important" and they have a good sense of humor.

When your (girl) friend asks to go on your shoulders, lets say at a concert or festival, and she isn't wearing any knickers, she subsequently gets the back of your neck wet, officially making you Wet Neck Sisters for life. A bond that can't be broken.
