Murdoc Niccals is the badass bass player for the kick-ass band Gorillaz. He is a Satanist, and will bring doom to you all. Kind of looks like The Beatles after a green day, and far too much alcohol. Has pointy teeth. Kickass.
The kind of person who has no boundaries, is always getting into trouble, does insane things on a daily basis, and is overall not the person you want to be involved with. They've got a huge ego and think they're above the law, so they'll do everything from steal, lie, cheat, beat someone up, get into car crashes, light stuff on fire... maybe even murder a dude if they felt like it. Just a big-shot who you shouldn't trust your car-keys with, or anything for that matter. Named after the insane bass guitarist of the Gorillaz, Murdoc Niccals.
Person 1: Hey, guys! The bridge is out! Let's go drive our car off of it and see what happens!
Person 2: Uh, that seems like a really bad idea.
Person 1: Oh, come on, pussy! What are you afraid of? Just jump out if the car catches fire and you'll be fine!
Person 2: Yeah, I'd rather not die, thanks.
Person 3 (to person 2): Don't listen to Murdoc over here. He's nuts. Let's just go get breakfast.
The use of the word "blue" to refer to sexually explicit content was first recorded in Scotland in 1824. "Blue" meant "lewd" because prostitutes dressed in blue gowns.
