On one end of the social spectrum we have the Upper-Class Twit proving that money doesn't make good people. But that doesn't mean a lack of money does the same. This trope deals with the various varieties of lout, hooligan and delinquent that appear in various media. While these stereotypes are Truth in Television to some degree it's debatable whether the stereotype comes from Real Life, or said real life examples are imitating the stereotype. A typical Lower-Class Lout is a usually (but not always) white teenager or young adult (with the occasional Enfant Terrible) who embodies the worst stereotypes of the working class (or middle class) which can (but does not have to) include;
Aggressive xenophobia and nativism, frequently blaming immigrants, especially illegals, for all of their country's woes. Occasionally overlaps with white supremacist/neo-Nazi sympathies.
Having sex with little regard for the consequences.
Dealing in and/or doing drugs, especially hard drugs.
Speaking in a rough accent peppered with "urban" colloquialisms that actual black people would find pathetic and obnoxious at best and downright offensive at the worst.
A distinct lack of hygiene, both personally and in their homes. Suburban and rural examples are particularly bad with the latter, with lawns covered in garbage, scrap wood, junked appliances, the rusting shells of inoperable vehicles, and various perpetually unfinished projects being a very common sight.
Driving around in a modified car (with mostly cosmetic upgrades) with an obnoxiously loud speaker or exhaust system and poor regard for the rules of the road. Rural examples tend to drive horribly dilapidated trucks with offroad modifications that greatly eclipse the car's book value and are frequently illegal.
Wearing (fake) designer clothing (often of a specific brand) with tacky (and fake) jewelry.
Having inadequate formal education.
Being incredibly violent and partaking in anti-social behavior.
A tendency to blow any and all windfall money received on garish, tasteless garbage, as well as having an aggressive "fuck yours, got mine, so bootstrap your ass up" attitude towards the less fortunate once they come into said money, regardless of whether they worked for it or not.
Because of the Unfortunate Implications the stereotypes imply, subversions are almost as common as straight examples, with a snobby or elitist character being established as such by having them accuse a sympathetic character as being one of these.
Various parts of the world have their own individual versions. Indeed, it's an interesting fact of crimino-sociology that nearly every society in the world with urban and youth culture has a certain stratum of "difficult" young people, especially men, which draw attention in popular culture.
A chav is a stereotype originating in British media. Their preferred fake brand is Burberry, and their slang includes such words as; "innit"note "...is it not?", "Safe!"note "Wonderful!" and "Sorted!"note "Done!" or "Ah, we no longer need to concern ourselves with this matter.", "Brap! Brap!"note An onomatopaia for the noise made by a TEC-9, typically combined with a pair of Finger Guns being fired into the air Gangsta Style. Other names (that might be used depending where you are in the UK and may have slightly different criteria) include charva and scally. "Pikey" might also be used to describe them, but was originally a slur directed at Travellers (and may be recognised as such).
Australia and New Zealand have a similar stereotype known as a "Bogan", who tend to be more middle class and less inclined towards theft. They are also more likely to self identify as a bogan. Other regional variants on the term include 'chigga' in Tasmania, note Named after the suburb of Chigwell, 'bevan' in Queensland, 'booner' in the Australian Capital Territory, 'scozza' or 'lexie' in Victoria, 'divo' in New Zealand.
The term 'westie' in Sydney is similar in that it generally means lower class (as the West of Sydney is away from the seaside and aren't as rich as the Eastern suburbs) but a westie will not necessarily follow or refer to the bogan stereotype. This is also found in Melbourne, Brisbane and Auckland. Inverted with Perth, where it is the east which is more lower class.
A related term is "hoon" (hooligan + goon)note Goon: cheap boxed wine, which refers to irresponsible drivers who speed, drink drive, and do burnouts. Most hoons would probably also qualify as bogans.
Ireland calls them "skangers", but chav is becoming more popular.
Similarly to "pikey" "knacker", which is usually directed at Travellers, is now mainly used to describe any example of this trope.
Scotland has "Neds" (which are similar to chavs, although some argue distinct).
Russia has its equivalent in "gopnik"note a term originating from "gop-stop", slang for street mugging. Etymologic principle is the same as for beatniks. Gopniks wear Abibas, Nyke and Puwa, drink cheap beer, eat sunflower seeds, are obsessed with mobile phones (more often than not acquired by mugging) and laughably stupid and violent. Some occasionally become full-fledged bros, most of them either grow up or piss off the wrong people and wind up in a gutter somewhere. Particularly stupid ones frequently try to pretend that they are either actual bros or have big-time connections, and they're usually the ones who wind up dead when they run afoul of the real deal.
Japanese Yankees/Yankis would fit. The pop culture portrayal being "violent low-class delinquents given to speaking roughly, wearing tacky fake "brand-name" clothes and jewelry and driving heavily modified (and also tacky) motorbikes/scooters". See Japanese Delinquents.
America has several types, although they tend to be regionally based. The exact slang used is different, the exact labels might be different, including the "Guido" stereotype sometimes applied to Italian-Americans in the mid-Atlantic states, as well as the less-flattering stereotypes one finds in Boston about Southies. Oh, and rednecks. Let's not forget the rednecks (who are heavy on the racist thing, but less likely to wear tacky clothing. Unfashionable, yes, but not tacky). Also their urban equivalent, "gangstas" (less racist, more tacky). There are also "refs", who are generally specific to South Florida (though any area with a heavy Cuban diaspora will do), who are stereotyped as being vapid, overly materialistic, extremely vain, and singlemindedly obsessed with partying and the club life, with tacky attire (lots of tracksuits, wifebeaters, and gold chains) and music (almost always exclusively a mix of Latin pop, reggaeton, and pop-rap) both showing up. Finally, we have "bros"; while this term is also used to refer to spoiled college-age upper-middle-class males, the lower-class example takes the form of redneck-ish douchebags from rural (occasionally suburban) areas who obsess over pickup trucks and SUVs with myriad modifications that are ostensibly for offroad purposes, but seldom actually see any offroad use, as well as watching excessive amounts of UFC and listening to a mixture of pop-country, Nu Metal, radio rock, and pop-oriented hip-hop. Tacky clothing is also common, with Tapout, Affliction, and Fox Racing all being common brands, along with items bearing the Monster Energy logo, and their dialect is frequently an indecipherably-slurred mix of "urban" affectation, profanity, and homophobic slurs.
Israel has "arsim" (male) and "frehot" (female). Aside from standard Lower-Class Lout stuff, they are known for being extremely racist (Israeli Arab Conflict aside, quite a problem in a country where 1/3 of the domestic population are immigrants of some sort), drinking too much (in a country that doesn't drink much), always trying to rip others off for money, being of Mizrahi Jewish or Arab descent, speaking a "low Hebrew" dialect completely unintelligible to more educated parts of society, not being able to speak any English as a consequence of not completing school, calling everyone "bro" or "sister" or "man", ending every clause of every sentence in "like" until ending the sentence with "man", and listening to hip-hop music. They are also the national self-stereotype of Israel.
In Iran, there is the "javat". A typical javat speaks with a peculiar accent, acts tough, and has a silly haircut and baggy clothes.
Mexico has two varieties: the "naco" and the "buchˇn"note also called "Manguera" (hose) in Baja California.. The first one might be of either gendernote "Naca" would be the term for a female one, is loud, uneducated, unrefined in fashion senses, speak using only Double Entendre and weird puns, watch only Soccer matches (or a Soap Opera if they are female), and they might or might not be a delinquent, or just poor and pretending that they have money. The other one is almost the same, except that they are Always Male, are smug, cocky, wear tackier clothing and jewelry than the first one, listens to Narcocorridos, and acts as a hammy drug trafficker. The Buchˇn is more likely to get itself killed for pissing off the real narcs.
Spain has "cani" (male) or "choni" (female). Its members sport mohawk-esque haircuts and big amounts of golden jewelry, listen to reggaeton and underground flamenco, and love Soccer and motorcycling.
France has both the "beaufs", often lower to middle-class, have "American" given names (KÚvin, Brandon, Jessica, Kilian, Jennifer, Jordan etc); loves cars, sports; crappy pop music and bad reality shows; as well as the "racailles" or "wesh-wesh", delinquents who live in public housings; wear mostly tracksuits and caps; only listen to rap music and are often blacks or arabs.
The 2007 reboot of St. Trinian's featured chavs as one of the school's cliques.
Most of characters in Attack the Block are youths in a South London street gang. In the first scene they mug a woman, but get more sympathetic characterization later, when they're saving the world from aliens.
The cast of Kidulthood and its sequel Adulthood (Katy from the first film seems to have been more middle-class, but still behaved this way.)
British horror film F is based around such characters going on a murder and torture spree at a school after being given failing grades by their teacher.
The Cherub Series features quite a few teenagers that display chavlike characteristics.
By Harry Potter and the Order of the Phoenix, Dudley Dursley has basically turned into one of these. Ironically, his parents have been, throughout the whole series, a terrible example (more like a parody) of the rich end of middle-class.
The Diary of a Chav series.
Shad Ledue in It Can't Happen Here. Even after rising up through the ranks of the Minute Men, his tastes and temperment remain coarse.
The Ewells from To Kill a Mockingbird. Filthy in both hygiene and morals, they live in an extension of the town dump, put only the barest amount of effort in, and treat everybody like garbage.
Jerry Cruncher in A Tale of Two Cities. He's a working-class moron whose abusive relationship with his wife is played for laughs. A Running Gag is his "spiky" hair, which suggests a disheveled appearance. Throughout the story, he's contrasted with the erudite main characters.
Some appear in Unseen Academicals, including Juliet's brothers and Andy's posse. Can't have a book about football without the hooligans, can you?
Onslow, Hyacinth's brother-in-law on Keeping Up Appearances. Obviously, Hyacinth is thrilled. However, while shabby and slovenly, Onslow is friendly and benign—and actuallyreally smart—and deliberately makes a favourable contrast with the snobbish Hyacinth.
Rebel Wilson seems to have made a career out of playing these kinds of characters (in films such as Bridesmaids and Pitch Perfect).
His day-job being doctor at a hospital in a very poor part of London, Theodore Dalrymple's writing is chock full of accounts of the people he treated, many of them for injuries incurred through their own bad decisions.
The Kankers from Ed, Edd n Eddy. Three half-sisters raised by a single mother, living in a trailer park, getting the kicks out of tormenting everybody else and sexually harassing the protagonists, with very little redeeming qualities.
Quite a few residents in South Park, especially in the earlier episodes when the town was much smaller and more conservative. Most notably, Kenny's family.
