'quickie' is also used to describe a non-sexual 'quick thing'. ...but it needs to be clear what that thing is from the context. If you just use 'quickie' on it's own then no-one will have a clue what you are talking about. It's more of a description than a noun. A slang word really...

Are you going to be working late again tonight? I hear you've got to finish the McPherson report...

No, it's just a quickie. I'll be done by 5.
