Yummernation

A period of heavy relaxation which a person enters after school is finished. The word originates from a combination of three words, Yelena, the word’s creator, summer, where most yummernations occur, and Hibernation, a synonym for emphasized rest. During a yummernation, a person tends to hide in their room with an abundance of fast-food, a TV remote, and a bathroom nearby.

Bro… what are you doing tomorrow night?!

Sorry, I am in a yummernation. Will, hopefully, return to you before August.
