Cawfee

Ok, this is really interesting to me. I think what you're trying to say is that you have the cot-caught merger, but for anyone who doesn't have this merger (like me) "cawfee" would be pronounced exactly the same as standard "coffee". For me, "caw" as in a crow cawing is the same vowel as in "caught", not the same as in "cot" which is the vowel I associate with the accent you're trying to convey. So it's not so much the direct intent behind your spelling, but the fact that you incorrectly think that someone like me would pronounce "cawfee" and "coffee" differently which outs you as someone who doesn't disntinguish "caught" from "cot".

Or I'm completely off-base and don't have any idea what you're trying to convey with "cawfee".
