MoCo 

Montgomery County, a Maryland county on the edge of D.C.. It's just about the most diverse place in the entire country and has arguably the best school system. It ranges from working class all the way to extremely wealthy and everything in between. You'll know the wealthy when you see them because the kids look ghetto then you see their mom pull up in an Audi. Don't listen to anybody saying the county's ghetto, that's just the schoolkid wangsters trying to act like they've even seen one when in reality they're just looking at a decent working class neighborhood. If you don't play lacrosse you know too many people who do. Overall, a pretty nice place as long you don't stay too long and don't run into all the wannabes, and can stand said wannabes making a racket drag racing all damn night. Seriously, there's not a time you can wake or a place you can go and not hear that din of the roads. Just keep in mind: don't expect a single turn signal and do not put the old bay on the fries, whatever they say. It's fucking disgusting.

P1: I went to MoCo, it was pretty nice but nobody will shut the fuck up.
P2: Yeah, just don't stay there too long. You'll go crazy.

MoCo 

County in Central Maryland, bordering Washington D.C. Full of many rich people that wish they actually lived in the ghetto. Someone, please tell them to stop posing. There are some ghetto areas, of course, but the county tries its best not to let other people know. Montgomery county supposedly has great schools, but they're just puffed up. They just have the money to get better computers, that's all.

MoCo Kid: Yo yo whaddup dawg?! West Bethesda, yo!
PGCounty Kid: *smack* Your mom drives a mercedes to pick up the mail. You are NOT in the ghetto.

moco 

A county located relatively close to the D.C. Area and includes some of the blackest white people ever conceived on earth. If you are not of above average intelligence, you will most likely begin to emulate black culture around the age of 12, and by 14 you will be a straight up thugged out gangsta, who just happens to live in Olney and isn't actually a gangsta at all. The majority of the white male population in Montgomery County truly belives in their heart of hearts that they are black men, and will do anything to prove so. These activities are including but not limited to the following; smoking obnoxious amounts of weed, drinking until they black out/puke/crash a car, wearing clothes that are clearly 3 sizes too large, driving like morons, speaking like a mentally challenged black person, and saying the word "pilt". The best thing to do is avoid eye contact with these whiggers, because if it is made, the string of words that follows is neither comprehensible nor english. In conclusion, Montgomery County is horrible unless you're rich, and even then, your children will try to act like they're black and poor.

Yo them MoCo bamas be pilt up this junks.
Ey yo it's the MoCo Po!
Yo MoCo's gots the finest 13 year old bitches.

moco 

MoCo is another name for Montgomery county. I've lived in MoCo my whole life and i found out about 2 weeks ago that MoCo is known in the country for kids dying from drunk driving, and girls gettin trains ran on them because they have low self esteem. MoCo is split up into different sections, the rich section, the ghetto section, and the country section. But no matter where you reside, you say you're from D.C., you act ghetto with your rich ass car, and you have beef with people from Bmore

person #1: where are you from again?
MoCo resident: MoCo represent niggaaaa! You dont know about that joint!
