cluster B personality types 

cluster B personality types include narcissism, borderline personality disorder, antisocial personality disorder, histrionic personality disorder, etc. Impulsive and unpredictable personalities, as opposed to cluster A and C personalities, which tend to be odd and eccentric (A), or anxious and scared (C). In my opinion, the most dangerous personality disorders are probably cluster B.

Person A: "Did you see Cory? He faked a broken leg for attention, he's been moaning and groaning about it all day long, but, he's actually perfectly fine!"
Person B: He always acts out like this for attention and disrupts his classmates. The school psychologist said he could have a cluster B personality disorder, like histrionic personality disorder.
Person A: "I heard that cluster B personality types tend to be described as impulsive and unpredictable in the DSM 5. "
Person B: "Yep, I hope he grows out of it."

Butt Cluster Bomblets 

You already know what this is...it's when you're trying to take a massive dump and the turd bomb reaches the sphincter only to release tiny little bomblets. They usually are responsible for that machine gun poop that splashes your ass. It feels like you're pooping Raisnettes.

Mikey: Man, I must've flown over Hiroshima in my previous life.

Mo: Why would you say that?

Mikey: Cos I just killed the camode with my butt cluster bomblets!

Freakish Cluster Bear 

The Freakish Cluster Bear is the most fearsome creature ever known, by any being, celestial or otherwise, it killed Jesus, birthed Satan, skull fucked Chuck Norris and shit on your mothers chest. At first there was nothing, emptiness, cold. Then there was the Freakish Cluster Bear, rampaging through the cosmos creating Heaven, Hell, Earth, God, Satan, Buddah, Shiva and Allah. They sprang up from the virtual oceans of fear, let forth from the stars. It is foretold that, at the end of time, the Freakish Cluster Bear will be released from his bonds by the Chosen One, who will rise up among men to free the Creator. The Freakish Cluster Bear wil then take up its run through the cosmos and decimate all in its path, cleansing the world of all non-believers and those that are unworthy, creating a new utopia for all of his children to thrive and prosper in for all of time.

Accept the the teachings of the Chosen One and let him lead us to utopia of the Freakish Cluster Bear.

The second coming of the Freakish Cluster Bear is upon us.
