There are certain SGA characters *cough*john&rodney*cough* who I want to call "cocky," but I always get stuck on the word "cock." And I'm like, "John Sheppard is cock, uh -- that would be likes cock -- no, no, I mean he has a, uh -- what the hell am I even talking about, again?"
*sigh*
But that wasn't, I guess, as bad as the time someone on an SGA community said they secretly thought Rodney liked to cook and I was all, "of COURSE Rodney likes cock! Duh! That's not much of a secret here on the internets!" and then I realized OH, that was so not even what they had said. In my defense, it was only one letter off AND had to do with putting things in mouths. And they were talking spaghetti and sausages, and just, SAUSAGES, okay?
In conclusion: SGA fandom makes me a lot more spazzy than HP fandom.
I can do you one better. My brother and I were at costco, eating lunch with an old friend's mum (she used to babysit for us!) and discussing SGA. I had a moment when I tried to remember the word colonel but all I could come up with was man-whore, so I went with it (its not as though the bother wouldn't know who I meant). Friend's mum (the evangelical christian) took it fairly well considering where the conversation veered at that point (when the train of dirty thought leaves the station, I'm always on it).
