How do I politely ask a girl for a one night stand or insinuate it?

You tell her, with a smile on your face, that you are a really easy lay. You tell her that you like casual sex. The important thing is, you are just honestly telling her where you stand, and she can make up her own mind whether she's interested. If she likes you, thinks you're fun, then she may well be into it. For many women, a no-complications casual screw is exactly what they are looking for.

So in summary... don't ask her for a one night stand... that is an uncertain approach at best. Instead, tell her that you are up for a one night stand, that you are open to the idea. That subtle difference is important in terms of how she thinks about it. Instead of saying "I want this to happen", you are saying "This can happen, if you want it". And she'll let you know if she's into it.
