I messed around with an "import killa" TA some time back, he didn't have much but he was a nice guy atleast. He said he got his stickers from the guy with the red TA/yellow flames "import killa" they must be starting some club.
side note:
How can someone with a stock v6 have killa anything on his car, maybe he shoulda put "getting killa'd" instead. That is more practical.
