I loved it when southerners asked me to "Mash the switch"
Like I was going to get out a sledge hammer to turn on the lights.
Sorry to interfere with your mashing, but one mashes a button, not a switch, so unless you have very old-style two button lights, you're flipping those.
I pictured this:

That's a switch, seems like you could mash that.
You're right. Didn't think of that sort, but if any were around me I'd totally ask people to mash it (that's very much a part of my own dialect). As are several things mentioned here:
My floor currently needs swept.
While I don't outen the lights, I am ashamed to serve store boughten bread to guests.
I use y'all more frequently but y'uns sometimes, and my older relatives use it more than I do.
I often tote stuff in a poke, but I know better than to buy a pig in one (the idea is that it could be sickly or even be something else entirely; one should always inspect the pig).
I also will red up the place if company's coming.
