Query about slang "scootch"-- Why -ch?

[FRITZ JUENGLING]

I personally have never heard any of these words, but asked a colleague of mine from around the Portland area and this is what she wrote in answer to my Q:

do you know the word 'scootch'?

yes, but I personally use "scootz".   I think "scootch" or my variation "scootz" is almost exclusively used as an imperative.  Has your list mentioned that?
