having a rapping contest against someone else in front of an audience, where most of the lyrics are insults directed at the other rapper which have to rhyme at the same time.

1 rapper goes first, then after he's done its the other persons turn and then someone decides whos was better, or after the second rapper has finished the first one can go again if he has more to say.
if one of the rappers suck at rapping they can get boo'd off stage by the audience. (they usually let some of the audience come up and take the mic for a few minutes at the end)

A hyper-egotistical poetic war of words and linguistic play.
The following is an example from Epic Rap Battles of History, a YouTube series

Miley Cyrus:
Let me guess, You're just here to hate
Well you can stand in the autograph line and wait
Cause I'm all twerk, I got all day
To Spit harsh words in this French maid's face
You died a virgin girl, who you think you're messing with?
It's Miley Cyrus, I'm the hottest thing since Britney, Bitch!
I'm getting lifted on that molly, get that party turned up
You getting lifted on a stake, get that body burned up
Had enough? It's my habit, when I grab the mic I milk it
You could say this rap is like my alter ego, cause I killed it!

Joan of Arc:
Lord, forgive me for the words I speak
I know the voices of the angels tell me to turn the other cheek
But I'm about to rip Hannah Montana's tongue out through here teeth
Je suis la fille en feu call me Katniss Everdeen
When it comes to bad bitches, I'm the patron saint
But I only get down on my knees when it's time to pray
I came to Frenchmen's aid in the time of need
Cause I'm the Maid of Orleans, You're the Mardi Gras beads, honey
My father taught me things your daddy couldn't teach ya
Your highest calling was a text from Wiz Khalifa
You gotta die for something, Miley, just picture your epitaph
Had the world watching, chose to show them all her flat ass

A rap battle is when 2 rappers go head to head and use intricate, and creative punchlines. They may use metaphor's, name or word play, or personals. There are on beat rap battles such as the ones that take place on BET'S 106 & PARK. Or acapella, where they rappers spit without a beat. There are several acapella rap battle leagues taking the game by storm such as, Grind Time, URL, Dont Flop, and Fight Klub.
Here are some examples of punchlines used in a rap battle said by well known battle rappers.

Loaded Lux: "Bitch you aint a crip ill make you flip like a jolly dolphin/ Lie on a track, die on ya back with the trolly chargin/ broke ya neck now, poke ya chest out like Dolly Parton"

Iron Solomon: "Im the one thats causing fear/ when Harry set up this battle he was like Paul Rever/ The British are coming the british are coming/ But history proved THE BRITISH ARE NOTHING!"

Farnum: "See i know lies and 90 percent of yo stuffs cooked up/ now i respect NY legends like pun but that dont make you a crook cuz/ yeah you from Queens home of 50, Nas, and Mobb Deep but look son/ I battled Many Men, But it aint hard to tell, that im battlin a shook one!"

Hollow Da Don: "Yall could believe him im coochi/ I got the word in philly he spark the tooly/ He grab the M16, Let off the Uzi/ Shiiit on call of Duty!"

Unlike an argument, a battle designed to be comical, racy, and being savage to one another until someone can’t come up with nothing.
Aaron: What is a rap battle?

Me: A game that some think it is similar to an argument, but is completely different. A rap battle is mainly comical, racy and one is supposed to commit savagery to win whereas an argument is losing when retaliating.
