Go for it! It is just an emoji... Unhappily, it seems to display a bit differently on different devices; on some it looks like a rat, on some it looks like a mouse... too much above my pay grade - pauper! On a hat or T-shirt that wouldn't be a factor, would it?
Ha! On my small device it looks like, well, a turd giving emoji life to “democrap”.
I’m sure that can be created, too.
