verb + off of

To say "Get it off my hands" is very natural English, but it would technically be considered a colloquialism.

I think you can omit the of in this particular case. If you leave it in pronouce it as one word: "off-uv"

Honestly, being a non-American, English is just as hard as learning Russian [I'm Ukrainian, but you'd think I was born here *wink*]. There is so much slang and word shortenings that it's crazy. You can say both "get it off of my hands" or "get it off my hands." -Get it off of my hands- sounds a lot more urgent than -get it off my hands-, so say whichever one you really preffer. You'll be understood either way [and here I was almost typing understanded...way to go, proper English -_-]. ^_^

It's fine but it is a collocation that's used more in speech. It just adds a bit more emphasis to a sentence.
