That be when two slut ass bitches start from opposite ends of a row of guys and suck there way to the middle. The slut that sucks the middle guy off first is crowned the biggest slut.
When I was at the bar the dj said it's time for the go down showdown,

This is a song from Lemon wich describes the battle between almost every hero in the world. It all started with Godzilla 'hopping' around Tokyo city. Then came Batman, Shaq, Aaron Carter, Abraham Lincoln, Optimus Prime, Indiana Jones, Chuck Norris and many others.

This song can be found with video on Newgrounds.
The Ultimate Showdown of Ultimate Destiny

Old Godzilla was hopping around
Tokyo city like a big playground.
When suddenly Batman Burst from the shade.
Hit Godzilla with a Batgrenade...

...This is the ultimate showdown
of ultimate destiny.
Good guys, bad guys and explosions.
As far as the eye can see.
And only one will survive. I wonder who it will be...

...Angels sang out in an immaculate chorus,
down from the heavens descended Chuck Norris.
Who delivered a kick,
wich could shatter bones,
into the crotch, of Indiana Jones...

...war went on for a century,
many lives were lost but eventually
a hero stood, the rest saw the better.
Mister Rogers in a blood-stained sweater.
