Glad to help the info-challenged.

The Buffalo Bills? What's a "Bill"?

Just a guess here but I believe it's a play on Buffalo Bill Cody, though he has no obvious connection to the city.

BUFFALO BILLS -

Buffalo’s team in the All-America Football Conference (AAFC) in 1946 was the Bisons. In 1947 a contest was held to rename the team, which was owned by James Breuil of the Frontier Oil Company. The winning entry suggested Bills, reflecting on the famous western frontiersman, Buffalo Bill Cody. Carrying the “frontier” theme further, the winning contestant further offered that the team was being supported by Frontier Oil and was “opening a new frontier in sports in Western New York.” When Buffalo joined the new American Football League in 1960, the name of the city’s earlier pro football entry was adopted.

What is a Hokie? The origin of the word "Hokie" has nothing to do with a turkey. It was coined by O. M. Stull (class of 1896), who used it in a spirit yell he wrote for a competition.

Here's how that competition came to be held. Virginia Tech was founded in 1872 as a land-grant institution and was named Virginia Agricultural and Mechanical College. In 1896, the Virginia General Assembly officially changed the college's name to Virginia Agricultural and Mechanical College and Polytechnic Institute, a name so long that citizens shortened it in popular usage to VPI. The original college cheer, which made reference to the original name of the institution, was no longer suitable. Thus, a contest was held to select a new spirit yell, and Stull won the $5 top prize for his cheer, now known as Old Hokie:

Hoki, Hoki, Hoki, Hy.
Techs, Techs, V.P.I.
Sola-Rex, Sola-Rah.
Polytechs - Vir-gin-ia.
Rae, Ri, V.P.I.

Later, the phrase "Team! Team! Team!" was added at the end, and an "e" was added to "Hoki."
