Sibling squiring

Getting your siblings to back you up in an online argument

Look at her, there's no way she would have said that. Her brother must have had her sibling squiring again.

sibling smashed

Similar to friend zoning but with the added insult of being "family" (love you like a brother/sister).

Him: You know, I really care about you.
Her: Oh, and you know I love you like a brother.
Friend: Ouch, sibling smashed. That's gotta hurt.
