A sarcastic description used to describe obviously phony, "hardcore" fans of either rock music, "nu-metal", or "punk" rock. This comes from their own tendency to purposefully misspell words in "cre8ive" ways in an attempt to be trendy. Calling one a "rawker" may go completely over their head.
"Dude, did you see that yuppie buying spikey arm cuffs and ties with her mom's credit card? She's such a hardcore RAWKER!"
