1. (adjective) A building whose components are built off-site (prefabricated), then assembled on-site. The quality of these homes ranges from cheap-ass trailers to the multi-million dollar modular buildings. Prefab homes are at the cutting edge of contemporary architecture (especially green architecture).

2. (noun) A person whose opinions, behavior, style, and/or tastes are determined entirely by others. Prefabs often do not know what the fuck they are talking about, as they rarely take the time to think through what they have been told.

3. (adjective) Of or relating to a prefab.
1. "A Honda Prius pulled up into the driveway of the new prefab home on the block."

2. "Bono indoctrinates the prefabs."

3. "The prefab protestors, unable to adequately respond to the harsh criticism, resorted to name-calling and accusations of racism, sexism, and ungodliness."

Something prefabricated, especially a building or section of a building...

manufactured in standard sizes to be shipped and assembled elsewhere; "a prefabricated structure"

In construction, a prefabricated house is produced in a factory, shipped out to building sites, and assembled by folks unequipped to design anything better. The prefab conservative, or prefab-con, brings the same attitude to political discourse: rather than using reason and critical thinking to craft arguments that fit the real world, he trots out prefabricated memes, arguments and conclusions that are passably functional at best. All too often, they are even worse: the typical prefabcon lives in an intellectual house of ugly, wobbly walls that collapse on themselves in slight gusts. Undaunted, he throws up another structure on the same spot, though that wolf named reality is standing right there, ready to huff and puff again.
Our generation has witnessed several prefab-cons, including, but not limited to, Sarah Palin and John McCain.

British popband consisting now only of its founder Paddy McAloon, one of the most underrated songwriters ever.
Do you know Prefab Sprout? Sure, "When Love Breaks Down", "Bonny", "Cars and Girls", and "The King of Rock 'n' Roll" are all great songs.
