a vitela means one who lacks skills in Call of Duty. Vitelas normally are found in the nicest parts of areas trying to act out as a "thug" when they really are not. Vitelas eat the penis's of much bigger stronger men and worship phony gods they call by the names of K-Blow, Teblow, and Moreneblow. Vitela's are normally and angry species because the fact that their shlong is way below the national average.
