Last week in my community group meeting, someone used the phrase "anal-retentive" and someone else asked if a nicer word could be used. We tried "detailed," "nit-picky," etc. and found nothing that worked as well. And a few of us (those discussing the matter) don't find anal-retentiveness to be a bad thing (metaphorical use of the term, not literal.)
This morning I read the following statement on a blog: "...those who are by nature precisionists (or anal retentive)..."
I thought the guy made up the word "precisionist" but I just found it at Merriam-Webster.
