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.
