It's very rare that you'll ever see me doing it online, as I only really ever do it if I'm really upset, and it's just generally much easier to control on here. It's a bit worse IRL, since it's pretty much just a habit I've developed from the people to surround myself with, and it's an easy way to express yourself, but it also depends on the people whom I'm talking to. If they don't curse, I'm less likely to, and vice versa :p But despite that, I'm not someone who's much for cursing at all, and really try to limit myself in any situation, though I have no idea why I feel that way :p
