The best way to refer to your wife's friends.
I could have gone to the Super Bowl if it weren't for you and your fat friends.
A girl or guy you keep around to make yourself appear more attractive. They usually have some outstanding quality like humor that makes them worth having around.
Bertha is funny,sweet and smart but she is my fat friend so everytime we hit up the club i get all the guys and the attention.
A grossly overweight and bitter young woman who finds a social outlet by becoming “Best Friends” with a much more attractive girl then manipulating and ultimately controlling her life to live through her.
Extremely hostile to most of her attractive friend’s friends and especially all of her boyfriends. Will interfere constantly with the view to splitting them up by any means necessary.
Will constantly “Feed” her victim until she’s approaching the same weight category and level of unattractiveness.
Dave: "She was alright, that bird
. You slipped up there, Jim."
Jim: "Wan't my fault, Dave. It was her fat friend sticking her oar in."
The obese/chubby friend of a hot male or female that can always miraculously keep them out of a relationship with you. The best thing to do with them is to friend them, then start a relationship up with your target. Afterward, do something that will cause the fat friend to split up with your lover, so that there will be no more of her/him.
Dave: My god man, that woman is soo hot. The things I'd do to her...
Jason: Good luck, man. Her fat friend always pulls her outta here before you can do anything.
