I don't cuss almost ever. Maybe a little when I'm extremely irritated. I think that if you know me and suddenly hear me cuss you'd be kinda shocked, like you would know that I'm really irritated now.
I mean there's a few very mild words that I don't even count as cussing, they are just adjectives to describe that something is bad to me, but if you count that then I still use them quite seldomly I think?
