siddler

Someone who will often appear next to you without warning. This is often done in silence and when you turn around that person would be next to you. They also often butt into conversations the moment you finish talking.

Adam is such a siddler. Whenever I'm talking to Aidan he just appears and starts talking the moment I finish. I never have any clue when he will be next to me.

sibler

A way to reference your sibling -- similar to brother or sister, but gender neutral. Can also be used as a term of endearment (Hey, sibster, what's up?). The plural, "siblers," can be used as a shortened version of "brothers and sisters."

I called all four of my siblers today to see who was going home for Thanksgiving. My oldest and youngest siblers will be there, but the other two staying home.
