A local cop who attempts to act "with it" and "hip" by using street slang from 2-3 years ago.
Said cop may also try to lure you into a false sense of security so you can admit your wrong-doing by using phrases like "that's whack" and asking why "you be fronting". His insistence in using the proper form of the word "fronting" (correctly said as "frontin") may be a good warning sign that you are faced with the Hip Hopfficer.
He may occasionally get confused and use slang from his own time by referring to something as "boss" or "gnarly".
Though you may be tempted by his offer to "sit down and rap", this person is in fact not your "homey".
"Yo dawg, I hate those Hip Hopfficers thinking they all that! That shit is whack yo!"
