A coworker always adds way too much to everything she does, in (what I think is) the effort to appear smarter and just oh-so efficient.
Using multi-syllabic words when one syllable will do. "Utilize" instead of "use" is an everyday occurrence.
Adding "solution" to the end of most processes. "It's our document copying solution" instead of "It's a copy-machine".
Adding way too many checkpoints when describing a process. Over-simplified example: instead of "Hey Bill, please tie your shoes", you'd hear "Hey Bill, those leather coverings that go on your feet, you need to take the laces...you know, those string-like items that secure them tightly to your feet...you need to take the left end of that lace and cross it over the right end of that lace and then...".
I need one word to describe these over-the-top actions. I feel like I have one on the tip of my tongue but can't find it. "Obsequious" is close but I think there's something better.
