Tea Party Patriots Official American Grassroots Movement 

A corporate-funded astroturf campaign disguised as a grass roots movement. A movement who's main objective is to further enrich the top 1% through various subversive means such as cutting the top tax rate (which is already the lowest it's been since the 1920s), and which has little agenda otherwise.

The Tea Party Patriots Official American Grassroots Movement is actually just a disingenuous attempt by the billionaire Koch brothers and Fox News to shift the country's economic policy further in favor of wealthy, powerful elites, ignoring the fact that such policies under George Dubya led to the Great Recession.

Grosseries 

A collection of various foods, all of which are disgusting and foul tasting, that were recently purchased from a grocery store. Usually purchased by a inconsiderate family member/roommate who's soul personal taste and food preferences, and not yours, were taken into account.

Tim: I'm really hungry and we have nothing to eat but stale crumpets.

Andy: Don't worry, Bridget just went for groceries.

Tim: Oh no!, all that bitch ever buys is GROSSERIES.

Grossery Shopping 

Act of attending a grocery store to obtain food and other necessary supplies without attending to any basic hygiene such as a shower, deodorant, washing your face or anything else one would normally do prior to going out in public and handling errands.

We went grossery shopping early Saturday morning to beat the crowds but we were totally scummy because we just got out of bed and headed down there.

grassroots 

meaning "of the people, for the people" originally used and abused by hippies.
and the word became unanimous with any and all political movements in the USA.
since it's inception it has became the best example of Semantic satiation as the word has lost all meaning due to the frequency of use.

"we must start a grassroots movement to show the government we mean business." -some hippy
"this business is so grassroots." -some starbucks hipster
"the band started as a grassroots, then eventually became the funk rock band it is today." -some nonsense magazine
