British slang words

[taylovesthebeatles]

Just wondering what is up with the Brits using the ou in words when it is not needed?

You know what I mean.

Color > Colour

Favorite > Favourite

That kind of stuff.

If you want to explain it to us yankees.

Please do.

You now have permission.

I'll stand up for eejit on this one, lol. We're the ones who got the language from the Brits in the first place, remember? So we're the ones who decided it's not needed and unnatural and decided to change it.

As to why though, I'm not sure.
