Nicely done, CM2DD. Great research and super examples!
I admit, upon reading your sentences, they do sound completely normal to my A.E. ear.
I wonder why I ever doubt that anything at all pops up in A.E.
People here can do and write just about anything and it's acceptable, or so it seems to be.
For example, coining a verb from practically any noun is nearly automatically dictionary acceptable, especially if a publication such as the New York Times does it. A property I appreciate very much about English.
May I ask, CM2DD, are you a B.E. speaker?
If so, is the expression 'smack dab' used in B.E. as well as A.E.?
I should have added re my graphic bird poop example, 'dab' can also be omitted, especially in situations which connote a 'splat' or similar sound, also otherwise.
"A pigeon just got me smack on the top of my head!" –referring, of course, to what it dropped.
"Jonny, look here! You left your toys smack in the middle of the hallway again."
And figuratively (time-wise):
"He came flying into the lecture hall smack in the middle of my speech."
