Basically a quick question. Consider the phrase:

I’m trying to almost literally translate a widely-used expression from my language to English, but it struck me as something a native English speaker wouldn’t say (as well as most of my pathetic attempts, sadly).
The phrase you have in quotes in the title is totally proper, even common in the US. However, use the term, quickie, with caution. The term can have a meaning that’s not really proper.
