You're reading way too much into it. I use it in certain situations where certain posters who dislike me try to get under my skin. I use it otherwise if I like a post.
That's where you're misunderstanding this place. I don't think anyone here dislikes you. On the contrary, I think people try hard to get along with you- without compromising the banter that makes these places fun. We like to poke in your cage and you seldom fail to deliver, ya ol knucklehead.
