Dont laugh but mine is from when I was a little kid. Was raised right next door to my grandpa and he drank coffie all day long, I was not allowed to so I had hot tea instead. When I was about six or seven I got a freash cup and on my way to the table I split it on his lap and he yelled "HOTBURN" and after that he always called me hotburn, but him and my dad and uncle were the only ones to call me that. 76 year I was born. First got to site and all the names I tried to think of were used up so I used that old one.
