A pikey is now-a-days usually a person who can't afford to be like everyone else. They do what they can for what little money they get and get on with life while all the Poshys
( people with money to spend like water) spend their money like water.
Chavs are genrally called pikeys but theey're not. They're chavs. Bling wearing, tracksuited, cap wearing chavs who enjoy saying "innit" and "bruv" and being whores/rentys.
