"Denial of Service" is a type of attack against computer systems that makes a server become unresponsive to any user requests. This is most commonly performed by flooding the server with huge amounts of senseless requests so that the server gets busy computing all those requests.
Normally, a denial of service attack does not compromise the server's security.
The "Anonymous" Hacker group recently started a denial of service attack on paypal so that no one was able to buy stuff via paypal for hours.

Denial December is a monthly challenge in the spirit of Simptember, Locktober, and No Nut November. During the month of December, each day you must edge to the brink of orgasm in the amount of days that have passed in December (15 orgasms on December 15, 16 on Dec. 16, etc.). If you cum during the month, you fail the challenge. YOU MUST DENY YOURSELF ORGASM FOR THE ENTIRE MONTH TO SUCCEED. Good luck, have fun.
Soomin: Dude, how's your Denial December going?
Jacob: Oh no bro, I failed that shit yesterday. I did better this year, but there was no way I was making it past 12 orgasms.
Soomin: Only 12? Yesterday was the 18th.
Jacob: Yeah, I just couldn't hold it in anymore.

When a town or area is flooded and all the people whose homes are destroyed go back in a week later and rebuild it. Many think it will never happen again even though it has occured several times in the last few years. Most take handouts from the government when major flood event happens and complain when they have to do anything to help their situation.

A vicious cycle that occurs every wet season.
Local Official: “Sir, your home has been flooded up to the eaves and there is black mold growing in it. You may have to relocate since this is a dangerous home in a high hazard area.”

Homeowner: “It never flooded here. I’ve lived here 20 years and no water has ever got in my home. That black line is a new decorating technique from France. ”

Local Official: “There is a fish flopping in your Lazy-Boy.”

Homeowner: “That’s my son Billy.”

Local Official: “It smells like mildew and mold in here.”

Homeowner: “Potpourri”

Local Official: “It will flood here again.”

Homeowner: “It will never flood here because that levee will never break. They just rebuilt it again for the fourth time and it is stronger than ever. You are just trying to harass me. Living by the Mississippi River does not pose a threat! This is all a government conspiracy. I only had water around my house, not in it. Now give me my money! ”

Local Official: "You are in flood denial."

Homeowner: "What flood? It's never flooded here."

The state you find yourself in when you refuse to believe summer is over. There is snow on the ground and your still wearing shorts and a t-shirt.
Person 1: Dude, what is he thinking it it's -4 out and he's wearing a Hawaiian shirt?
Person 2: He hasn't come to terms with the weather yet.
Person 1: Winter denial?
Person 2: Winter denial.

Either one of two things:

1.(n.) When a person (usually overweight) can no longer fit into clothes of a particular size but continue to buy and wear clothes of said size, despite what their gut/hips might have to say about it. Typically occurs when a person refuses to accept that they've either become fat, or(in the case of an already lardy person), have gained even more weight.

2.(n, abstract) When a person who may feel a touch insecure about the size of their..."thing " buys condoms larger then they are.
This often leads to slippage.
1. Suffering from a classic case of size denial, Jack continued to wear his favorite size 30 jeans, despite the fact that his waistline bordered size 38.
(please note that this phenomenon is more prevalent in women.)

2. Luke wanted to buy condoms, but he when he found out he was "Garden Snake" size, his size denial kicked in.
So instead, he grabbed the Anaconda ones instead.

A guy/gal who denies that they are emo to avoid even more ridicule from their peers, thus creating only more reason to ridicule them. True emo-kids deny that they are emo because they do not wish to promote the fact that they are emo. An emo poser would promote the fact that they are supposedly emo.
Brad: "what are you crying about you little emo-girl?"
eM: "i'm not emo!" *sobs*
Brad: "you are such an emo in denial."
eM *wiping tears from under her sideswept bangs,
murmurs* "..am not."
