What is "tigernado"

Between May 5, 2015, and May 10, 2015, 127 confirmed tornadoes - ranging from EF0s and EF3s - raged through Oklahoma and surrounding states. The tornadoes were accompanied by flash floods, severe thunder storms, and a few minor earthquakes. The death toll was 7 ( 5 from the tornadoes and 2 from the flooding). Grady County, Oklahoma, experienced four of these tornadoes on May 6. One of the EF3 tornadoes grazed over Tiger Safari located in Tuttle, Oklahoma. Due to this, Grady County was under strict warnings about the possibility that the tigers, and other creatures, might have gotten out of their habitats. This spurred the creation of the term "Tigernado."
"Tigernado" is a mash up of "tiger" and "tornado" as "shark" and "tornado" form " Sharknado." There tends to be word mashing in this region of the United States. " Oklahoma itself is a portmanteau: "Okla" and "Humma" mean "Red" and "People" in the Choctaw Indian language. There are the cities in Oklahoma that are portmanteaus of "Oklahoma" and the bordering state nearest the city: Arkoma (Arkansas) and Texoma (Texas), and also regions: Arklatex (The region where Texas and Arkansas border Oklahoma) and Indiahoma (Region in central Oklahoma honoring native tribes).
