The M.A.C. System

The M.A.C. System refers to a remarkably simple system that every male puts into effect at one time or another. The M.A.C. stands for:

M-Move in
A-After
C-Completion

In short, once one of your friends is done or broken up with a girl, you silently move in to support the girl in her time of dire need. Crushed and heartbroken, the girl will talk incessantly, but will eventually open up sexually. It can be noted that this system requires almost minimal effort and simply nodding and listening works, combined with a few hugs.

The M.A.C. System was made popular by Mac, a fictional character from It's Always Sunny in Philadelphia. His system is highly underrated and deserves as much attention as the D.E.N.N.I.S. System.
Example #1

Dennis: "What is this swooping in business?"

Mac: "Oh that's my system,The MAC: Move in After Completion. I wait til you're done with them and then I swoop in, give them a shoulder to cry on, then we hump."

Dennis: "You've been humping these girls after I'm done with them?"

Mac: "Oh yeah dude! I'm swimming in your wake."

Example #2

Robert: "Hey, Charlie, you get laid this weekend?"

Charlie: "Yeah, Mike broke up with Holly on Thursday so I used The M.A.C. System on her and we made sweet, passionate love."

Robert: "No kidding? Bump it."

U Street D.C.

The area near Adams Morgan where you drink pabst, eat eritrean, hear jazz, go to Black Cat or DC9, and try not to step on rats.
U Street D.C. is best likened to city haunts in Philly, Pittsburgh, or Sacramento -- i.e. not really that hip, but maybe a good a thing because it's very hot so no one really wants to wear pants so tight.

C.C.A. Baldi Middle School

The best-rated middle school in Philadelphia, largely due to the overly strict rules of discipline and uniform. Located at Verree and Marchman roads. It combines the puny, slightly innocent 11-year-olds, with the much more mature and perverted 14-year-olds whose main topic of conversation is pubic hair. Most children spend their first month figuring out the circular hallways and the dizzying amount of staircases. The word 'detention' does not exist in the 7th grade world, it's a suspension or nothing. The building is either extremely cold or extremely hot. Russians and Mexicans make up most of the population.
C.C.A. Baldi Middle School is an utter piece of faggotry.
