Someone who gets angry at everything all the time and won't admit it.
Donny: OMG LOOK AT JOHN HE'S SO ANGGGRYY
John: No I'm not I'm not angry god dammit! Stop it or I'm going to tell on you!
Donny: ANGRY CHAVS!
Someone who has their last name with the letters "CH" in that order. They also must always be angry, even if nothing is wrong. Thus having an angry chav.
John was angry that James haxed his computer. John then got up and kicked James in the shin and laughed. Thus being an Angry Chavs because he's so mad.
