I've even got my friends into the habit of anding the '-y' and '-age' suffix onto the end of words, I do it so frequently. I tend to use quotes an awful lot, no matter who's around. I remember once in Science class there was a discussion going on about weird relationships and I butted in with 'Love makes you do the whacky' - I'm almost sure people thought I was insane. But, I use Buffy quotes a lot, though, and the dialogue; I, too, use words such as 'wiggins' in everyday conversation, despite the fact I usual have to explain what it means.
