cockroach
A version of English spoken by inner-city Blacks consisting primarily of the noun "Mofo" and the verb "Mofo". Incomprehensible to pasty-faced white folks.
Urbanite#1:"Yo mofo, mofo mofo mofo mofo!"
Urbanite#2:"That's so, Mofo."
Confused Honkey:"What the fuck...oh, they're speaking cockroach."
