F.S.A. (Free Shit Army)

The F.S.A. is used primarily to describe "the 47%" of US citizens who not only pay nothing in federal taxes, but actually believe that they are entitled to the fruits of the labors of others. It is also used to describe a large portion of the Democratic Party who rely on the government to provide food stamps, subsidized housing allotments (Section 8), and sign themselves up for every bit of free stuff possible (also see "Ghetto Breeding Machines.").

You can often identify members of the F.S.A. (Free Shit Army) by their SNAP/Food Stamp cards, latest urban fashions, Section 8 Housing voucher-stubs, their $300. Nike tennis shoes, Apple Smartphones, and their 60" Plasma televisions.

F.S.D. 

F- Fake
S- Scene
D- Dome

This is typically, but not always a girl who is; 1. Fake (hair-dye, bape loving, pot smoking, I go to concerts to look cool, and such) 2. "Scence" (I like to hang out with guys who are in bands, I listen to screamo music, and wear a ton of band tee's) and 3. Like to give dome (dome meaning head). Other types of people like this could also be known as a groupie. F.S.D. people have no life and can be seen at every party, playing beer pong, and attempting to break up relationships. Be cautious, these people carry S.T.D.'s.

Ex.1: person1: Liz iz so F.S.D.
person2: No you have her confused with Amanda

Ex.2: Look at those groupies, they're so F.S.D.
