A lower-functioning subspecies humanoid that usually inhabits subterranean dwellings, and enjoys frequenting Wal-Mart. They tend to chiefly subsist on some form of government/taxpayer assistance. Also, their young are typically referred to as hatchlings.
"Did you get a load of that troglodyte?! She just tried to buy beer with food stamps...and right in front of her fourteen children (hatchlings)!"
A person who lives away from the coasts and metropolises, once referred to as a 'hinterlander' but no longer deserving of that otherwise-dignified term. He regards himself as a "real American" and his culture as that of such. He is adamant about his Second Amendment rights but isn't very interested in those other, less-relevant amendments that only the judges and politicians- who he scorns as being "leeches"- care about. He hates the idea of more laws, government or regulation of anything that reduce what he regards as "freedom", itself a word that he flings about without care. He hates non-real Americans, i.e. American citizens who are unlike himself, and those who he hates the most passionately are Muslims, all of whom he associates with the 9/11 attacks. In his telling you what's wrong with the U.S. and the way things ought to be, he could endlessly expand this definition without even knowing he is doing so.
Troglodyte: indoor-smoking, hard-drinking, pickup truck driving, Muslim-hating, liberal-hating, foreigner-hating, homophobic, gun-loving, self-assumed Christian who hasn't set foot in church in "only God knows when".
