When I was 13 years ago making my dA account I asked my little brother at the time 9 years what my user name should be, he said, "coolestawesome10" I'm terrible at naming so I went with it. At the time I was a hardcore brony so I often be in the chatrooms rping with others, they often complained my name was too long do they said "Coolesta" instead, for a while I went with it until one day I decided to at Mr. in front of my name, from that day on I went by the alias MrCoolesta
