Constructor's CommentsThis is a pretty common type of theme: words that fall into the same category either starting or ending a phrase. The trick is to use the word in a different sense. I'd been thinking of the various terms for cutting foods, so my original title had been "Kitchen Cutups."
I'll admit that "hash" is probably iffy here. It can be a verb but probably isn't used that way very often in the cutting-up sense. HASHTAG was just too good a central entry to pass up.
