TerraKill is no TerraPin!!

So, recently my little brother came running to me urging me to follow him to his bedroom to see his new pet.
so im in his room expecting it to be a nice new fish in his tank, but its not! Its a lovely little terrapin no bigger then a Zippo lighter, i ask his name "TERRAKILL" he replays excitingly, "And william how exactly did u come up with this name" i asked him, "ive just thort of it" he replays with a huge grin on his face, "so you didn't happened to just see it plastered all over my room when you just came to my room got me?!?" "No i just thort of it" he replays, "surreeeeeeeeeeee you did, and you didn't just see that name in my room yeah?", "no honestly i just thort of it" he replays again, eventually he admits seeing the name in my room, and as harsh as it is i made it quite clear that there is only one TerraKill in this household and its ME! not no hard shelled pet.
After a little refusal to change the name, he decided to call it.......FATBOY. lol?
