forced sibling

A sibling under your age who you didn’t ask for to be born or your parents had without asking you.

Melissa: Kaylee has a forced sibling, how sad.
Jessica: I bet her parents don't care about her anymore.

Liquid sibling

A sibling of darkness.

Your liquid sibling is trying to scare everybody again. He/she is too chicken shit to say/do some of that shit in real life, but will show up in a video game as a video game character trying to fight you.
