What do you think of these 15 obsolete words?

Laura Moss writes that we should be resurrecting these 15 obsolete words.

First, I don’t think “slugabed” is really obsolete. I’m sure I’ve seen it, and maybe even used it myself. It definitely sounds familiar.

Second, is “younker” to mean young person really obsolete? Or is it regional? I kind of had the impression it was rural / southern / regional somehow, and perhaps somewhat old-fashioned, but not actually obsolete.

Third . . . I must admit that I am not familiar with any of the other words on that list. I’m not sure I believe in them. Have any of you ever heard any of them used? Were they ever really in common usage? Actually, I don’t like most of them very much and I’m pretty much okay with letting them slip away into the past, if they were ever in general use in the first place.

Except “Cockalorum.” I must admit, I like that one.
