The UnderGround 

Also called the UG. A message board forum for MMA (Mixed Martial Arts) fans and fighters. Members often refer to themselves as UG'ers. Contains many UFC and PrideFC elitists/nuthuggers that hate TUF noobs(new fans due to The Ultimate Fighter Reality show). Members tend to belittle others for liking certian fighters, or for not knowing who certain figters are.
There are different levels of access to the forum, a free or MUDNAMER account and a Pro account(blue, green, red name)which costs $$.
Mudmaners usually get shit on by the Pro UG'ers for not buying a name (forum namism if ya ask me).

Ban this mudnamer, The UnderGround doesnt need anymore TUF noobs.

The Ultimate Sloppy Whopper Combo 

This one is the most tricky of the sloppy whoppers, you need to get a group of friends to gang up on one victem. each performing different variations of the sloppy whopper. you must stick you penis in a burger, get another friend to get his penis in his or her mouth while she yawns, and the third friend to ejaculate on her back. Any one who can pull this off is a lord of the whopper.

We are so gonna get John back for all this. THE ULTIMATE SLOPPY WHOPPER COMBO!

Center of the Universe 

The intersection of 119th Street and Indianapolis Blvd. Do to its proximity to Chicago, during the 1930s this was one of the busiest intersections in the country. There was once the architectural landmark of the Illiana Hotel but it was demolished during the early 90s. The only remenant of its long vibrant history is one of the orginal White Castles. Even though the term is used sarcastically by young people in their twenties, there are remenents of truth in it.

Hey lets go hang out at the Center of the Universe.
