When someone you are interested in goes one step beyond friend zoning you and tells you that you are like a sibling to them. Also see "sibling zone". Being siblinged is permanent.
Guy: What happened last night as your dinner with Andrew?

Girl: We were having such a great time, laughing and sharing all these things we have in common. But then I got siblinged.

Guy: What do you mean?
Girl: He literally said to me "We've got so much in common, you are basically a sister to me" - So, thats one step past the friend zone.

Guy: Oh that sounds like Andrew...
