Looking at the translation and adaptation of children's books, we found this in one of Lucy M Montgomery's Anne books from the early twentieth c.:

"Confound Corcoran! If he couldn't put his meaning into less dangerous phrases he'd get into trouble some of these long-come-shorts."

I've never seen this word "long-come-shorts", and have not been able to find it in my dictionaries. I can understand the meaning being something like "one of these days", but is it a standalone word, or do you only find it in the expression "some of these long-come-shorts"? Is there a singular form? Where does it come from, and how did it get that shape?
