Old, crusty, or worn out.

"Look at that old bag o' bones over there. She's really festered out."

Broken down; out of commission, on the fritz.

"What happened to your car Sally? Oh, it's festered out again. I think my hubcaps are bad."

What happens to a large pimple with a big white head that grows in the middle of your back that you can't get to.

"Dan what the hell's that on your back? It's all festered out."
"Tish used to be a good lay in the sack, but now that everybody's had a jab at it, she's all festered out."

Get the festered out mug.
festerville;

a city of festers;

the crowd at a Guns 'N' Roses concert (which is ironic really, considering the term partly emerged from the corruption of their song lyric 'Paradise City');

when too many ex-'Greenpeace' members (expelled for smelliness and total lack of personal hygiene) congregate in one area (well I just couldn't say all Greenpeace- after all, they did
"t-r-y", not stopped, but "tried" to stop whaling- hey what the hell are my donations for then!);
"Whoa man, let's get the F n G outa here, it's a goddamn regular festerville up n in this!" panics Sad,
"Yeah Saddywah, those R.E.M. lovin' tree huggin' ferals over there are making my olfactory senses internally vomit, nuthin' but festered-out-city ", observes Zack.

Get the festered-out-city mug.
All-Festered-Out: All smoked out. Having smoked enough marijuana and don't want or need anymore. Can't get any higher.
No thanks. I'm all-festered-out!
