Aww, you chunk.
Guy 2: Yeah bro, you know.
Chunkster dress in crazy styles and have similarly crazy hair. They might wear a mixture of chav clothing and a punky hairstyle for example.
Chunksters talk however they want, but it usually has chavvy words in it. They also do what's known as a chunk touch, a mixture of the "rock on" sign and what's known as the "touch", or "spud".
Unlike the typical stereotype of chav, chunksters usually are not dumb or delinquent, much like scenesters.
Chunksters may listen to emo music too, but are classed as chunk because they listen to some punk music (and other genres too) and don't wear oversized scene sunglasses all the time.
