A blackage is a group of black people on your porch knockin on your door unexpectedly. Like how UPS does when your takin a shit or preparin your drugs. Most white people NEVER take in a blackage!
When I opened the door to see who was knockin I noticed a blackage.
Refers to a black man's package, his penis, which is usually very large.
Man that cracka may be small but he's got a blackage.
