Sirblem

When a problem is so sir, that it becomes a sirblem. There’s also the higher form, known as Super Sirblem. Essentially the same thing, it just has even more sir, so the super is added to differentiate.

Example 1: And then I said, “Sir, what’s your sirblem?" And they laughed like sirs.
Example 2: Sir, I don’t see what the super sirblem is.

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.
