You are Police Lingo, the most prolific code-based talking-themed permanent-marker tagger around. Ten-four, you have multiple 187s on you and people around here copy that, but won’t dare snitch for fear of being 187ed themselves.
If people were to 10-29 you they’d find you’ve got a clean rap – you don’t get caught. Five-O gets called when people see you and run Code 3 to where you are but you’re 10-8 before they ever get 10-97.
When people see you pull out that sharpy, they know what 10-36 it is. It’s 10-36 for another sweet tag. Maybe on a table, maybe in a bathroom stall. You don’t pick just any old 20 for your art. You’re Police Lingo.
