Merc 

The origin is from the noun, mercenary. A mercenary is someone who will carry out combat missions but aren't part of an official organization, like the military, or CIA and are usually not motivated by justice or an allegiance. (They are usually motivated by profit) Activities associated with these "rogue agents" or "guns for hire" usually involve violence, and often killing.

So the slang verb "merc" generally means to perpetrate violence, usually killing, but can just mean to beat someone up (usually to teach them a lesson/send a message). Or it can be used figuratively, as in, "that mc just got straight merc'd in that rap battle". Similar figurative expressions could be, "Man, he just got smoked!", "Dude, you totally slaughtered that guy", "Yo, she schooled that chick", "When my boy rocks the mic, he be killin' any sucka mc that steps to him".

Like many slang terms, there is an original way to spell it and variations on spelling that can become widely accepted (it is slang after all, so normal grammar rules do not necessarily apply). Merc is the origin spelling, whereas murc, murk, merk, etc are alternates. Like some people write murda instead of murder, dood instead of dude, or dat instead of that.

"You mess with my girl again and I'll merc your ass."

"We totally merc'd the other team in COD last night."

"A guy walked in with a gun and just started mercin' people left and right."

"I heard those old school mobsters would merc somebody just for looking at them the wrong way"

"Yo, I was spittin' rhymes in this cipher last night and this whack mc stepped to me, but I straight merc'd dat foo."

Marcia 

A beautiful name for a beautiful girl. She is extremely loyal, trustworthy, hilarious, kind, intelligent, charming, stylish, insanely gorgeous and cute, unique and the bestest friend anyone could ever ask for. She is beautiful inside and out. Marcia's are very modest and sometimes underestimated, often surprising you with her never ending list of abilities. Marcia's also tend to be very talkative but are also great listeners and give great advice. She is easy to talk to, very approachable and makes a great leader although you may not see it. Marcia's are very helpful and giving and are great if you need a person to muck around with or cause some trouble. You are very lucky if you have a Marcia in your life, or have them as a friend. Also note, although Marcia's have their bubbly, loveable personality, they are very tough so make sure you stay on their good side. She is the girl every boy loves and every girl admires. Even with her flaws, she is perfect.

'What do you think of her?'
'Who? Marcia? Love her'

Marcia 

Marcia is absolutely amazing. She is a beautiful girl inside and out. She tends to act tuff but is truly caring and has the best personality in the world. Many may say that Marcia is mean and disrespectful but that usually just means that they are not close to her. Marcia does not let people into her heart very easily but if your lucky enough to get there then don’t take that opportunity for granted because she’s fragile and has been through some things that not a lot of people could handle. You DO NOT want to be on Marcia’s bad side because just as she is nice she can be a psychopath!

Marcia is a beautiful, loyal, and kind girl.

Marcial 

An amazing guy that's truly like an iceberg. He can hide his emotions pretty well at first but beneath that cold but super attractive surface is a kind, caring, & loving guy. He's someone you fall in love with so easily because he always knows just what to say and knows how to keep his girl happy but never seems to open up at the right times... Whether you hear from him within a day or months later, the feelings you have towards him will never change, and his phone will always be dead. He's a successful, hardworking man that knows what he wants and goes after it until he succeeds. ♚

Annnddd... He's crazy amazing in bedddd.

That Marcial is so hot...

Walter Mercado

Someone who can sense the possibilities of others, but who may be unable to see the dangers in his own life because he is a dreamer. Walters are charismatic, kind and sensitive people, who should be cherished whenever you find them. Many are artists or spiritual people, wonderful to be around, and some are even quite fabulous.

John is a Walter Mercado, be nice to him because he won't always be around.

Mind of Mencia 

n.
The absolute worst television show ever aired, or, for that matter, concieved by man. It is a void, a black hole completly empty of any mirth or comedy whatsoever. It is a momentous failure of mankind and God. It is the humor equivalent of Absolute Zero; so blatantly unfunny that it can only be achieved through a controlled laboratory setting. This leads some to believe that Mind of Mencia was, in fact, created specifically as an experiment to find the most unhumorous idea possible, but it's hard to imagine that any but the most sadistic would even contemplate unleashing such an abhorrition as MoM on the world.

Also, vb: Mencian
Something so horrible it compares to the calibur of the unholy blight itself, Mind of Mencia. It has yet to be used seriously, because come on, let's face it, nothing is that fucking bad.

"Dude, that class was so bad...it was, like mencian." (It is as bad as Mind of Mencia)
"Woah, woah. Hold up. It wasn't that bad."
"You're right. NOTHING IS THAT BAD."
