A much slower solve than usual for a Wednesday. Possibly because I started this last night when quite TIPSY, and possibly because of a number of unexpected items in the fill. I don't particularly love OHOH (8D: "Call on me! I know this!"), ENVIRO (4D: Green person, for short) (never heard this, and I'm a green person), LACEINTO (9D: Give an earful) (not familiar with this term, either), or NEOS (36A: Modernists, informally) (yuck). And then there's more than a smattering of INRE, ETSEQ, AERIE, CGI, SDI, AMPM, NALA, GAEA, TAI, APR, NAE, VIN, AND REN. All of which, NATCH, put me in something of an UGLY frame of mind.
But then there are such lovely entries as SCHERZO (23A: Lively movement), SNUCKUPON (11D: Caught unawares), ONEOFF (25D: Something not repeated), and ERUCT (51D: Burp). And I know some in my family will very much enjoy seeing GETFUZZY (39D: Comic strip featuring Satchel Pooch and Bucky Katt) in the grid.
As for the theme - changing the ends of familiar phrases so that they end up ending with "ET," and cluing them wackily - I usually like wackiness, but something just seems a little off with these. For starters, I don't like that the pronunciation of the end of "Vanity Fair" changes when made into "ferret." In all of the others, the pronunciation stays the same. But even with those I had problems. Is MOUNTAINDUET a genre? I know it's a play on "Mountain Dew," and I know "Dueling Banjos" is a duet… but is "mountain" a genre? I just don't get it.
I guess this one wasn't for me. Onward to The Turn!
p.s. 1A: "Oh, yeah …, " in a text (BTW) - F.
