1. the false belief that one has a nice bum

2. a belief which often causes one to flaunt their botton, when it in fact ought to be modestly covered
Sarah's sudden appearance at work in a pair of tights caught her co-workers off-guard, who were surprised that such a sensible woman had bum delusions.

A person who is loose or a whore, though completely denies such claims. This can be a purely outward denial or a true delusion where they believe they in no way differ from most others in sexual partners. This can be a problem in many relationships, since today's early 20's harlot is tomorrows late 20's wife. Many a poor bastard has been trapped by these sluts and not known until it was too late. A good sign of this is when she has been caught trying to fuck everything that moves and her partner becomes protective, she will scream and shout that he thinks nothing of her and she can't believe it. These can be tricky, they will never understand why their partners are so suspicions all the time. High stress relationships are the norm. Usually, everyone who meets one will know right away she is loose. Give off a strong whore aura (see - haura ). We all know those girls, two seconds after meeting them, we know.
Delusion Slut "I can't believe you would call me a whore! Why do you always think I slept with every guy I meet? God, I'm not gonna sleep with anyone jerk. I am a grown ass woman and have more self respect than that!"

Poor Bastard "You blew a guy in the park because he walked up to you and your friends and asked which one of you girls was gonna suck his dick"

Delusion Slut "That was a long time ago, I've changed"

Poor Bastard "One of my kids isn't mine, I had to find out at work from the girls in the office. DNA test confirmed it. It killed a huge part of my soul"

Delusion Slut "God, you need to let things go"

Poor Bastard "I hate you, you don't even know your a damn whore. Your a delusion slut. I'm gonna define your whore ass and see if I feel better."

Asian Delusion is a serious affliction suffered by many asian men. It is directly related to their futile attempt to convince the world that their penis' are just as big as that of other races when in fact they are not they are substantially SMALLER! Asian's use old fictitous proverbs and other propaganda in an attempt to convince their own people as well as the world that there genitalia is not the microscopic joke that it is. Many asians get so obsessed with perpetuating this lie that they actually fall under the delusion that there penis' are equal or greater in size to that of the white, black, or latino male when in fact they aren't. This lie is especially harmful to asian females in that it deprives them of the sexual pleasure they seek and deserve. When an asian woman finally experiences a non-asian penis she quickly slips into a phenomenon known as Asian Delight and vows never to entertain another asian man sexually again. Since asians excel at mathematics they should realize that numbers do not lie and neither do rulers! The asian penis will always take last place! Asian men need to realize that asian penis is smaller than that of every other race. The only people who are convinced by the myth that the tiny asian penis is not tiny are the perpetrators of the myth.
There are only three known ways to treat the affliction known as Asian Delusion.
1. The delusional asian must appear naked in front of a room full of non-asian women and listen to their hysterical laughter at how small their penis' actually are.
2. Measure their own penis with a ruler, then do the math. They always fall several inches shorter than that of the small end of what is considered average for other races.
3. Read all the definitions on Urban Dictionary and realize that EVERYONE knows about the tiny asian penis and repeat steps one and two until all signs and symptoms of Asian Delusion have disappeared and have been replaced with Asian Acceptance!

Illusions of grandeur - schizophrenic

Delusions of grandeur - crystal meth addicted
(Soliloquy to self) I'm enormously proud of that lecture I produced at the friar's club last evening. My delusions of grandeur had kicked in just in time for the thing to roll right off my tongue with such ease, power, effectiveness.

2) (social workers comparing notes) - "the boy ain't schizophrenic. He high on crystal, caught up in his own delusions of grandeur and shit.

Basically anyone (mostly 1980s and 90s kids but not all of them) who deludes themselves and thinks that the past decades they grew up in were a lot better than the current decade they live in now despite a lot bad stuff still happening in those past decades.
90s kid: I hate today! I miss the late 20th century so much! 80s and 90s forever!

2000s kid: When will you overnostalgic people learn that EVERY decade has bad things happen in them? Were you not old enough to notice the AIDS epidemic, the Lockerbie bombing or the eruption of Mount St. Helens which killed 57 people?

Or how about in the 90s if you were even aware of the Bill Clinton sexual misconduct allegations, the suicide of Kurt Cobain, the Columbine shooting, the Oklahoma city bombing or the rise of teen pregnancy?

90s kid: Yeah, but the music back then was SO much better!

2000s kid: At least I grew up in a time where I was able to access my favorite songs and albums faster thanks to the internet. I swear most of you 80s and 90s kids suffer from a serious case of decade delusion.
