Oh, haha, slang, ha.
It's actually really funny...I have an added problem with slang...or maybe its an advantage...I don't know.
I'm incredibly literal, yes, but I also don't see pictures in my head unless I think about what I heard. I see words floating by, like on a page.
So first, I hear the slang...then I see the words passing across my mind's eye...then, after a 3-4 second delay, I design a picture in my head because I just can't understand those words...oh, the pictures I get. By that time, the person who said the slang realized that I didn't get it...
So, I hear:
"What's up, dawg?"
I see first: w-h-a-t'-s u-p d-a-w-g-?
I then see the guy turned into a dog....or at least his head becomes a dog's head. The same with calling a girl, "chick."
My mind is rather entertaining, but most people think I'm stupid because of the "delay."
