I was sick or something while my friends were over and when it was time to take my medicine I either took to much or I dranks it with something I wasn't supposed to (mind you this was a while ago). My friends and I started playing a computer game and since I was all mellow and chill they put in the name, Medchill. It also has many easy variations, Medchiller, Medchilled, Medchilleh, Medchillie, MedKiller, Medchillem, Medchills so it kinda just grew on me.
