Surprised no one has mentioned the worst oxymoron yet: fast trawler! When I used the term fast trawler, I originally put it in quotes, but that got tiresome. Now I just try to avoid it when I can, but that's even more tiresome. It does serve its purpose, but it just seems so wrong.
But, let me brag about something corny, more annoying than fast trawler: I think i get credit, or more likely dishonor, in inventing the term "trawleresque.' I don't think I need to define it as it sort of speaks for itself although I might have invented it as a replacement for fast trawler. Worse and worser?
