So, for examle, execute Iconize[(a + x) y, "thing"]. Now you can copy/paste that icon into your NIntegrate expression. It'll look like a little gray thing labeled "thing", but it will really be the expression (a+x)y.

Just in case this might be what you want, there is an Iconize feature. If you select your (a+x) y expression and bring up the context menu, you can choose to iconize it. There is also the Iconize symbol. You can copy/paste this thing around the notebook.

If I'm understanding what you're asking for, the answer is "no". Variables don't really hold any contents. The Set (=) construct creates a rewrite rule in the environment. thing doesn't really have a value, it's not a reference to a memory location, for example. It's just something that the evaluator will replace according to the rewrite rule. Having said that, if the evaluator is running and encounters thing, it will immediately replace it, which is effectively "pasting its contents". However...
