Kuririn is his Actual name, (the food Pun on his name is "Kuri" which is Chestnut, the shape of his head) Krillin is a dub name made from one of Toriyama's Several Spellings in the Manga (Krillin, Klylin, Klilin. Kuririn) mostly because Krillin rolls off the tongue a little better. People use Either term tho, and neither is technically "Wrong", but there have been several people here calling him "Krillan" which is just wrong o_o
