I figured it was time for another RASH. You may think that that's far-fetched or that I am out of touch, but, well, here it is anyway.
As my previous RASH puzzles, this one is also based on JWCOREY's series of puzzles starting with GC2DX6M, which contains the rules for a RASH puzzle, so please consult them there, if you are unfamiliar.
One important rule: a dash (-) in the clue indicates no space between the respective parts of the solution, e.g. "I-am" could not become "you are" or anything else with two or more separate words in it.
