A person who refuses to get sucked into the superficial, MTV party lifestyle that his constituents tend to pursue. He lives his own life, ignorant of passing trends and other pseudo-cultural phenomenon. In other words, the "caz" is someone who lives outside of the world around him that has become over-saturated with falsehoods spewed out by the media.
I think I'll just go outside and get some sun instead of going to a tanning salon like everyone else. That's what caz would do.
I wonder why he doesn't spike his hair or get meaningless cliche tattoos. He must be trying to emulate caz.
Wait! You'd rather go kayaking than go to parties, get wasted and smoke weed all the time? You sound like a caz.
