When I was active, I would dream about killing Uwoiame.
I also had troubles going to World of Warcraft because they would get confused when I said I was a GM because there, a GM is a Game Master, and you just call a Guild Master a Guild Master.
I have caught myself saying Grin and Giggle and the likes as well.
The worst though has to be when you're a born and raised American and you start trying to spell color colour and favor favour, etc etc. Not to mention the British sayings and words like snog.
I also have to say it's pretty bad cuz I still get a kick out of saying oh, I need to go grab some DP, referring to Dr Pepper, but still thinking it's Divine Protection.
