“Veep” is the nickname of the vice president, from the initials V.P. The word “veep” was influenced by the 1940s popularity of the word “jeep,” often said to have been derived from the words “general purpose” and its initials G.P.
 
Vice President Alben W. Barkley (1877-1956) credited his children with the word “veep” in May 1949, saying “That’s what my children call me anyway.” The selection process of a vice presidential candidate is often called the “veepstakes.”

Wikipedia: Alben W. Barkley
Alben William Barkley (November 24, 1877 – April 30, 1956) served as the 35th Vice President of the United States (1949–1953), under President Harry S. Truman. A member of the Democratic Party, he previously served as a U.S. Representative (1913–1927) and a U.S. Senator (1927–1949) from Kentucky. He served as Senate Majority Leader from 1937 to 1947.
 
After an unsuccessful candidacy in the 1952 presidential election, Barkley was elected again to the U.S. Senate after defeating John Sherman Cooper in 1954. He died shortly afterwards in 1956 at age 78.

Vice President: “The Veep”
(...)
Barkley was popularly known as “the Veep”. His young grandson, Stephen M. Truitt, had suggested this abbreviated alternative to the cumbersome “Mr. Vice President.” When Barkley told the story at a press conference, the newspapers printed it, and the title stuck. Barkley’s successor as Vice President, Richard Nixon, declined to continue the nickname, saying that it had been bestowed on Barkley affectionately and belonged to him. However, the term has continued to be used as shorthand for Vice President.
