Jack Thompson 

Some major dumbass who thinks playing games like Grand Theft Auto will turn kids into killers and car-jackers.

News Reporter: Just last night, angry kids ran out onto the street, hijacked some cars, and then went to Jack Thompson's house and killed him.

Children of the World: YAY!!!

Jack Mormon 

1. A nominal, or non-practicing, Mormon.

2. A person born in a family with Mormon roots, but who does not live all the precepts of the faith.

3. A person not unfriendly to Mormons, or who might even believe some or all Mormon tenets, but who - while not being adversarial - does not participate in the sacraments of the faith, or abstain from proscribed actions (such as smoking, or drinking coffee, tea, or alcoholic drinks).

4. (Archaic) A person with many Mormon acquaintances and friends and/or who sympathizes with them and their beliefs, but chooses not to affiliate with the church.

"He's a jack Mormon, but if anyone's in trouble he's the first one there to help"

"She likes to go to Relief Society meetings, but she just can't give up her doubts about the Book of Mormon or her morning cup of coffee. She's a confirmed jack Mormon."

Jackson Heights 

Like its said before “the illezt “ town in NYC. A place you never seemed to be really bored. A place where every damn race or ethnicity seems to converge. Broken up into three sections, The Indian/Asian part, The Whitey Part, and The Hispanic part and you’ve been to all three. With a rival stores within a block range from each other like BK and McDonalds on the same damn block. Where your proud to show your true colors and proud to tell everyone where you came from. Living here its most likely that you have friends who are Hispanic, Asian, Indian, Black and White. Here we got the best food out of ANYWHERE, cause Bitch we got EVERY kind of food here! Here, you can be who ever you want to be, Gansta, Skater, Goth or just normal, doesn’t matter! Here is where you make the best memories of your life. We have the best of the best, no doubt bout that.

Guy: Yo bitch, where you from?
Girl: Jackson Heights motherfucker!
Guy: Dayum!
