In my music post, I mentioned that swearing in songs sticks out like a sore thumb. It's something that makes my ears immediately perk up.
I would say I am much more foul online than off. Swearing is apart of my digital vocabulary. I do it excessively online. I swear online without even thinking about it. Scaling it back wouldn't be a bad thing.
Offline, it's a different situation. Swearing isn't a sentence filler as much as it is for me online. By no means am I the Virgin Mary of bad words. I will drop a 'shit' if I stub my toe, for example.
Something that soured my view on swearing in real was my eavesdropping on some chick who was on her phone. I was walking into the shops, she was walking out. She was on the phone swearing like a sailor while pushing a child. I found it to be quite distasteful.
My family weren't hyper Christian goody two-shoes. Swearing is something my dad will do every two minutes. My mum does it less often, but it's still there. I've just always found it to be a bit weird. Especially in the case of people using it where it's not necessarily needed.
My dad always used to say the curse words were a sign of a poor vocabulary. So naturally being the little shit I was, I went out of my way to learn a bunch of wildly verbose ways of swearing.
It really just depends on my company. I'm old fashion in the sense that I wont usually swear around women or children, or in a professional setting, but around old friends I can sound like a marine with tourette's.
I agree though, if someone isn't trying to be funny or really make a point, I think its tasteless.
