Festerpool 

To think about multiple negative thoughts creating a festerpool of negativity resulting in situations appearing far worse.
A festerpool of high emotions can result in riots.

No School Foster Glocester!

As a kid just over the line from RI, I would wait by the radio on snowy school mornings hanging on every word of school closings that Salty Brine would call out. While most times my school had to go to school, *GROAN!* there was most always a school that made the no school cut. I can still hear Salty's teaasing voice as he knew we all knew what was coming shouting out with glee: "No School Foster Glocester!!" Who were these lucky kids...geeeez!?!? lol

Salty Brines most called out snow day was for No School Foster Glocester!

Foster Shuffle

An indescribable sexy dance which can only be properly performed by the lead singer of foster the people, mark foster. Although it may appear to be easy, this dance requires ultimate talent and skillful coordination, which is only fully possessed by mark foster himself. Do NOT attempt at home.

Person 1: You tried the foster shuffle last night!?
Person 2: Yeah, I tripped on my foot, slammed into my wall, and now have a slight concussion.

Fostertopia 

Communist empire founded by a band of enraged students and their world history teacher, Ms. Foster. Once established, the country began to conquer many a history class until the nation of Justintopia wanted a piece of the pie and stepped in. Led by King Justin III (twice removed), the country led a valiant fight until the mighty gradebook of Ms. Foster came down upon them, causing them to retreat. Shortly afterward, Fostertopia's "key republic" 5th Period World History (Pre-AP), signed a declaration of independence in rebellion of their dictator. The document was acknowledge, but freedom was never received. Today, Fostertopia lives in civil war as many loyalists and rebels continue to quarrel in the halls of Health Careers High School.

Long live Fostertopia!
