I have to admit, I didn't fully understand the theme until long after the solve, but that could be partly due to the fact that I think this was one of my faster Sunday solves. (Just over fifteen minutes to fill in all those little white squares.) At first I thought it was turning certain phrases around and making them into similes, as in "crystal clear" becoming CLEARASCRYSTAL. But that clue, "Bus?" Aha! It makes clear into a verb, and makes crystal into barware. Presumably. So, ok. That works. But "Photosynthesize?" for GREENASGRASS is a little weaker. I guess you could think of "green grass" as a thing, like in "Green grass and high times forever," but it's not a very common expression, and "green" as a verb is a bit forced, too. So it's not perfect, and the "reversing known phrases" probably isn't even part of it, but it's not terrible, and the puzzle had a lot of other good fill.
ANECDATA (Evidence derived from personal experience and observation rather than systematic research and analysis) was a fun one. I've never heard that before, but I like it. LABOROFLOVE (Passion project, perhaps) is lovely, OHSTOP ("You're embarassing me!") and IMAMESS (Cry from someone who's disheveled) were fun in the top middle there.
I was not familiar with a B-52 shot, but I now have learned that it is equal parts Grand Marnier, Irish cream, and coffee liqueur. Probably fine, but I'm not much of a shot-drinker. I rode SEPTA back when I lived in Philly (when HIGHTOPS were the only things I put on my feet), but I have not pierced my septum. Nor have I ever tried Imagine WHIRLED Peace ice cream.
One clue that seemed a little weird to me was "Exquisitely made basket" (DUNK). I looked up "exquisite" and found "extremely beautiful and, typically, delicate." Not exactly how I think of a DUNK.
I'm happy to be back on the reviews this week, and I look forward to tomorrow! :)
