Go home and have a bath 

An insult/really crappy comeback when non chavs talk to chavs (however this only works with the chavs who say they aren't chavs though, all the other ones will just hit you)

Jakky G:Don't talk to me you chav!!

Jack A (who fiddles with Malakie's genitals): Errrrrrrrr go home and have a bath!!

Jakky G:Go listen to that noise you listen to that you think is music!!
