MF DOOM 

Arguably the best producer and lyricist of the 21st century. Your favorite rapper's favorite rapper. All caps when you spell the man name.

What the devil? He's on another level
It's a word! No, a name! MF the super villain!

Yeah, you're listening to the buttery slickness
The Land-O-Lakes from my man MF DOOM!

Doom Slayer 

1. One of the most bad-ass demon slayers/killers to ever be brought forth into fucking existence.

2. Usually refers to your death multiplied by a very large number. If someone uses this phrase in a sentence, it means they are located within Hell in its deepest, darkest, and hottest pit, and still sensed you shit your pants.

Ok, Kyle ; (... I see how you want to go at it. Man, fuck super saiyan, prepare to face the wrath of the Doom Slayer, fool...

Doom Slayer 

In the first age, in the first battle, when the shadows first lengthened, one stood. Burned by the embers of Armageddon, his soul blistered by the fires of Hell and tainted beyond ascension, he chose the path of perpetual torment. In his ravenous hatred he found no peace; and with boiling blood he scoured the Umbral Plains seeking vengeance against the dark lords who had wronged him. He wore the crown of the Night Sentinels, and those that tasted the bite of his sword named him... the Doom Slayer.

The Doom Slayer is too angry to die

Doomba 

A Doomba is an amalgamation of the Roomba; a series of autonomous cleaning devices made by the company iRobot and various weapons such as knives, chainsaws and fireams which are strapped or somehow attached to the machine. The word "Doomba" comes from the merging of the words "Doom" and the previously mentioned "Roomba". This has recently become popular on various Internet sharing sites.

"Hey Johnny, I strapped some knives to your mom's Roomba, let's watch it go around the room."
"Yeah, now it's a DOOMBA"
