Oh yeah ok, I had something similar in mind:

Instead of having users search on one page and then paste to another, I would just have the search on the same page and once the gif is selected it automatically loads the input 

But now you got me wondering:
What about double tapping on the search page? Tap once to copy, tap again to meme?

It’s just that having a floating button over every meme that’s loaded looks clunky in my mind, but maybe I’m thinking about it differently
