Chiffalo (chicken + buffalo)

Papa John’s (a take-out and delivery pizza chain) introduced “Chiffalo” (buffalo chicken pizza) in September 2013. The term had not then been trademarked.
 
“Chiffalo” had previously been cited on Twitter on February 16, 2013.

@sohumpawar I think I like Chiffalo much better. It rolls off the tongue.

“Chiffalo.” Portmanteau of “chicken” and “Buffalo.” Sounds not delicious.
