When someone tries to dodge every social event by delaying their decision until they run out of time and then they start whining and saying that they wanted to go, but due to some made-up circumstances weren't able to.
Anyone: How about going to the ZOO?
Hung: Yeah, great idea, let's go next month!
*a month later*
A: Ok, lets go
H: Oh no, I soooo wanted to go, but unfortunately... the dolphins got killed yesterday.
A: Ah, yea, that's such a hungsterthing from you.
A portmanteau of hunger purgatory defined as the state of hunger with accompanied physical discomfort that makes you realize you took too long to do anything about. Now any cooked meal you would prepare or takeout you could have delivered will take too long and you will suffer until you actually do eat something. Usually this makes deciding what to eat even more difficult as a result which only exacerbates the problem
Opening and closing the refrigerator door doesn't make a ready to eat meal magically appear before you, you're in Hungatory now and it's too late. Your stomach will growl and churn in complaint for as long as it will take you to make something.
