A poor white supremacist with traits like that of a cockroach but can be found around the world spreading diseases poverty drugs etc towards low-income neighborhoods. Another word for cracker but with the addition of comparing one to the invasive insect that inhabits the ghettos alongside people of color and defiles their communities.
"WTF? Look at that Crackeroach around that block over there, Tyrone. Look at him trying to corrupt our cousinz by selling them weed pot crack and cocaine to destroy our developing community!"
Crackensack is what some people call Hackensack (NJ) because of the drug issues you can find in many parts of town. The city isn't really as bad as people make it out to be, but for the county it's in (Bergen Co, near NYC) it's a hot spot for people around the area to buy and sell drugs.
Hackensack is the largest city in Bergen County, NJ
P1- Yo, you know where i could score some crack and weed

A crackerjack box was the disposable cardboard box used to hold popcorn or candy (sweets), though over time has come to mean a similar box or container used to give away rather useless, cheap toys and/or giveaway items. So anything referred to as 'coming out of a crackerjack box' is being derided as useless, cheap or fake.
Did you get your degree out of a Cracker jack box? (ie. your degree in media studies / sociology etc. is worthless)
(From Meatloaf's "two out of three ain't bad"): There ain't no Coupe de Ville hiding at the bottom of a Cracker jack box (you'll never find a valuable and exotic, vintage car in the bottom of a crackerjack box)
