I curse in casual conversations, to emphasize my point or for fun with "f-ing" etc., but at the same time I can filter what I say and whenever I say it, so basically I use swear words, not really curse.
Some people curse all the time and they don't feel it.
Being a future English teacher, I'm planning to use some of the naughty words in class
Yeah, too much. To the point where it's inappropriate. Like I'll just drop the c-word casually and then straight away I'll be like "ooooh, ok, probably shouldn't have said that."
All the time to the point half of the time I don't realize I'm saying it. I remember I went to some place filled with kids, and I was doing something which I ended up saying 'F***' really loud, kids looked at me which from me realizing I said 'S***' and then 'F***' from again realizing what I just said. Never ran away so fast, a lot of parents were greasing me off.
Edit: Forgot that we still get censored, fixed up the words.
