Plump Sister 

A woman who has put on a few pounds since the last time that a random 72 year old Uncle will say to Larry, the cousin twice removed, this kind of thing:

Larry: "Must've been back in the Seventies. Before the kid. Kids. Who knows."

Uncle: "It was May 1979. When they got married...wow she just blimped out!" Larry: "Total butterball. Plump Sister, shame."

When a guy/ girl you like says "you are like my sister" or "you are like the little sister I've never had" or "I love you like a sis" It is worse than being friend zoned, it's all the way past friends to family. You probably have a 2% chance of getting out of the sister zone and having a relationship with that person.
