What 99.9% of all Urban Dictionary definitions are (unlike the .91% that are actually funny, clever and/or descriptive.)

A person who lacks class. Trashy people exist among all races and socioeconomic levels. Trashy people lack meaningful goals and purpose in life. They are not very concerned with academic subjects, worldly matters, nor culture, but are more amused with unimportant matters and simple activities such as celebrity gossip, shopping for useless merchandise (like cigarettes), and excessive partying into late hours. Other than spending money, trashy people contribute little or nothing to society, which is why they are associated with "trash". Due to low self-esteem and insecurity, trashy people inhale a lot of filth from cigarettes, attempt to overcompensate and "try too hard". Examples are wearing excessive amounts of make-up, wearing provocative clothing (whether they're in shape or not), driving a vehicle that is excessively large for their needs (e.g. a Hummer), getting drunk and behaving obnoxiously in clubs and bars, yelling at strangers from car windows, making derogatory statements, promiscuity, and talking loudly in profane and explicit language in public. Although they may think they're cool, most other people find them obnoxious, stinky, immature, irresponsible, and unattractive.

Trashy people are characterized by a hollow arrogance born out of insecurity and stupidity. Because deep down they know they are trashy they overcompensate in the following ways:

Trashy women think their bodies are much better than they really are and display a lot of skin, usually muffin top / fupa. They also wear gaudy skimpy clothes, usually too tight to draw attention to themselves. Tattoos can also be part of this.

At work they think they should be running the place after 3 days on the job and in spite of being complete fuckups.

Trashy people people are loud, boastful and have foul mouths in an effort to draw attention to themselves and sound tough.

Trashy people are selfish and not team players. Their only goal is to satisfy their needs and they think nothing of taking advantage of others to get what they want. They think this is the "American Way".

Because they are insecure, trashy people tend to follow the latest trends, no matter how stupid because they want to be accepted.

Because they are stupid, trashy people tend to smoke, being either unaware or uncaring how horrifyingly unclean and disgusting a thing tobacco is.

Trashy women have sex frequently and unscrupulously for power and attention.

very low and disgusting

1. Apparently, not being a hyper-elitist yuppie douchebag from the upper middle class or upper class.

2. Apparently, not aspiring to be a hyper-elitist yuppie douchebag from the upper middle class or upper class. (This aspiration is apparently synonymous with "ambition.")

Additionally, definitions like this one tend to get denied by Urban Dictionary while scores of others written by elitist yuppie dipshits who aren't "trashy" get passed with flying colors.
