Oh goodness, since we discussed this, I’m finding myself more aware of the things that escape my mouth without permission, lol.
It’s really a thing at home. Sometimes what I’m doing will remind me of a past interaction that I am resentful about. I don’t know how to manage it. What happens is that something really aggressive and loud comes out, like FUUUUUUUCK THOSE FUCKING GODDAM STUPID ASSHOLES! OH MY FUCKING GOD! DIE IN A FIRE!!! I have to hope the neighbors are not home or otherwise unlikely to notice.
Yesterday, I had a success, though. I knew it was about to happen so I stuffed the broad side of my forearm into my mouth to muffle it. This worked, so good deal.
I might or might not have a ball gag on hand that could make this easier. In fact, I got it for a similar purpose, mainly because I also grunt and vocalize loudly if I am doing chores or exercising in the place. I’m probably pretty weird to do that, but it’s less weird, IMHO, than traipsing around my apartment with a pair of socks handy to muffle my screams. 🫤
