I don't curse as much online as I do in real life. I'm not sure why. I think it's because I'm able to think what I'm saying more clearly. In everyday life I curse more than I say "umm". I don't even curse when I'm angry or upset, I curse more just in regular conversation. It's like it's just... how I accent my speech.
If I'm upset I can't even think of using actual cuss words, instead I turn whatever pops into my head at the time as a curse, usually sonofa followed by random words that I have no idea got in there, that or random grumbling. It's gotten to a point where my friends keep a list of my extreme curse monologues for future generations.
I am making a conscious effort to use curses less, but half the time I don't even know I'm using them.
It's just weird how online if I swear and it's not like 'wtf' or something. Like using it in a sentence is weird. Depends on the sentence.
Swearing helps, for me, create emotion in a sentence. Swearing doesn't always need to be a negative. Think of how much a difference there is in the feeling from "That's awesome!" and "That's ****ing awesome!". Feels completely different. Like whatever is ' ****ing awesome' is way more impressive.
Otherwise I curse worse than a ****ing sailor.
Random funny story involving swears. Friend of mine with a dirty mouth was getting owned in soccer. The ref threatened to red card him if he swore again. Very next play he hits the ball out of bounds, starts yelling "SHI-" then catches himself and finishes "-TAKE MUSHROOMS!" He got red carded.
