I hate it very much when people use the word fulsome incorrectly. In fact, I rarely see it used correctly these days, which makes me wonder if we are going to lose a very succinct and useful word to the inexorable onwards march of linguistic evolution. Damn.
In case you're scared to ask, "fulsome" does emphatically *not* mean "comprehensive" (don't get mixed up between "ful-" and "full"). It means something like "cloyingly insincere by excess", thus "fulsome praise" means praise that is too over the top to be sincere. Here endeth the lesson.
