MUNcest 

Intimate relations between members of Model United Nations (known as "MUNdoes," (em-U-en-does)), of which there are three degrees:

Third Degree MUNcest: occurring between MUNdoes of different committees at a conference
Second Degree MUNcest: occurring between MUNdoes of the same committee at a conference
First Degree MUNcest: occurring between MUNdoes of the same school/program.

While first and second degree MUNcest are in fact smiled upon in many circles, 1st Degree MUNcest is widely frowned upon. Those guilty of 1st degree are to be subjected to friendly teasing such that the crime may never be forgotten.

There is also a legendary and unproven MUNcest with ones chairpersons. Many dismiss this to be mere folklore but experts claim it is theoretically possible. It however has not been worked into the degree system and is largely shrouded in mystery and conjecture.

Natalie and Jordan committed muncest,

Manchester, MI 

Village in Southeast MI, home of the flying dutchmen. If you don't wear steel toe boots anda carhart on a daily basis and/or live on a farm, you probably don't belong here. Theres 4 half-black kids, so really only 2; and 3 asians who are adopted by white parents. 20 minutes west of the arrogant hippies of A2 and 20 east of the wankstas of Jackson, 20 north of the wiggers of Adrian, and 15 south of the coke heads of Chelsea, this small town is a unique buffer between these cities. You wanna party in Manchester? Drive around any night of the week and look for a barn thats lit up. Theres bound to be a game of beer pong and a joint being passed around. We don't even have a stoplight, so don't expect much, the Dairy queen doesn't even have chocolate ice cream. Supposeldy world famous for our annual chicken broil, town events revolve around the highschool sports or the Mens club. Theres 7 churches and 3 pizza joints in a town that rarely has over 100 kids per graduating class. Where will I be tonight? Hammies at The grey house. Yes sometimes we do actually party indoors even though with this crowd we probably should be outside.

After the football game, were gonna party in the parking lot in Manchester, MI

Manchester by the sea 

A place where every family buys there child a Jeep as soon as they turn 16.. the moms all go to book club together to drink and to gossip about their children and who’s dating who. If you don’t spin the beach in your free time then you really aren’t from manch. Summers revolve around the singing beach and people spending time on yatchs.

Manchester by the sea is where you should live if being preppy is your thing.
