I’ve seen more than once people tinning their solder irons by add some solder and flicking the solder onto the floor hard.

I did that for many years, and even hit my bare legs or feet a few times. But the solder cools really fast, and doing that doesn't cause a great deal of pain or damage. Just enough to remind you to be more careful.

These days, I flick the solder onto my soldering mat instead.
