I got started using — because the golems in Guild Wars 2 speak in all caps and with em dashes between the words.
I had to copy-paste after doing Alt+0151 somewhere else when doing the joke when using a golem transformation tonic and SPEAKING—LIKE—THIS since Guild Wars 2 does not respond to numpad input, but Mac users have it easy, they can just press Option+Shift+dash.

On Windows, you would need a tool like PowerToys’ keyboard manager or a keyboard macro for that.
