Is there actually a tag for one person lying on another one?

Well, there's girl on top but it's not very reliable.

Would it be useful inventing a more general tag, and if so, any ideas? I just can think of "on top of each other" and "one upon the other", but they are a bit too long in my opinion.

Make a Double Decker tag maybe?

Well, is there another suggestion?

Let me think Phin, 'superposed' perhaps?

If girl on top is not sufficient, just use on top?
