IC is police-speak for identifying the ethnicity of a person: identity codes include IC1 (White), IC3 (Black), IC4 (West Asian), IC5 (East Asian), but the term IC3 is used more specifically to refer to black males or an opp. BSide rapper '30' popularized the usage of this term in the song 'IC3'.
“We have one IC3 male, around 5ft 5in, wearing a black hoodie and a red baseball cap"
30: "On the lurk tryna fry me an IC3"

Get the IC3 mug.
The code word used by many walgreen's clerks far and wide, over the intercom to let a fellow co-worker know that there are more than 3 customers waiting in line. When "IC3" is called over the intercom, a co-worker will take some of the waiting customers at a seperate register, hence improving customer service.

IC3 = I SEE 3 (customers)


(4 customers waiting in line)

Cashier1: (over the intercom) "IC3"
Cashier2: (to customers) i can take some of you at cosmetics.
-customer service is boosted

KNOW YOUR SHIT.
