What do you know, it's Wednesday and we get an odd duck of a puzzle! Five "common" phrases where the letters TER are omitted from the end, and the resulting phrase is clued wackily.
So... I'm going to give nods of acknowledgement to the original phrases "Gimme shelter" and "straight shooter". These are well established. I guess "portrait painter" is fine, although it's somewhat ad hoc, as is "train spotter". The last I know better from "trainspotting", but I suppose to do that activity, you become the phrase in question.
I'd never heard of a "prairie oyster", but it Googles well. Let me just say for the record that I have no interest in trying one. Raw egg, worcestershire sauce, tomato juice, vinegar, hot sauce, salt and pepper. I'd be fine with that scrambled and cooked with butter and maybe a finely diced shallot, but not as a drink.
But I absolutely love the result of the puzzle's manipulation. 16A: Great Plains plaints? (PRAIRIEOYS) brings up the image of Lubavitchers on a covered wagon trekking to the west coast, kvetching all the way. Excellent. The other four are not nearly so interesting. PORTRAITPAIN's clue is directly related to the original phrase. TRAINSPOT is kind of boring. The reveal is good though. LETTERDROP, or "Let 'ter' drop!" Until I saw that the clue told you to split it into three words, I was trying to figure out which letter was dropped.
|OSAKA never looked so real|
1A: Bottom topper? (TALC) gets a B+ for the funny clue.
