Trashy women think their bodies are much better thanthey 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.
Trashypeople 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 whatthey want. They think this is the "American Way".
