I have to admit, my language has gotten coarser over the years than it really should be. I attribute it to a shifting of the focus of my patience while life experience has led to more long-lasting pet peeves. With more experience, relatively, under my belt, I begin to see the tropes of life; things like how common courtesy is becoming less and less common, how lopsided politics has become to the point if you don't hold popular viewpoints you can't speak out on your own without risk of ridicule. It grates on me, like a cut that won't heal properly 'cause it keeps getting small pokes every so often.
As a result, I find it easier to be patient with some things, like waiting in line, or an unexpected delay with something I was planning, than I do with things that seem to be the result of careless, thoughtless or callous behavior, like very casual insults slung at my religion or political viewpoints, or when I'll say something doesn't seem right in a game in the chat box and someone puts me down for it, then tells me not to be so serious when I come back on 'em for it. That's when the bird tends to come out of the cage and my tongue starts to get venom on it.
