Well, sometimes when people type like that I honestly don't understand what they are trying to say. I didn't know that fink was think. If it's really shorthand - they are only skipping one letter.
I thought they were talking about some kind of wild animal or something. I had to read it about 10 times to realize what that word was, and then I was like "duh"
the one's that confuse me are:
coz
fink
wat
wut
nd
omygah ( I thought this was a std)
i'm naturally naive though, so I guess it would make sense that i'd be too stupid to interpret this stuff. :) there are a bunch more that confuse me sometimes, but I can't remember what they are.
