A vernacular term for heroin (diacetylmorphine HCl) used most frequently in the Baltimore/DC ''High Intensity Drug Trafficking'' area.
synonymous with, and possibly a contraction of "Blows" (not to be confused with "Blow").
It is usually used to describe the most prevalent local variety of heroin, which is often presented as a mixture of 16-35% diacetylmorphine, ~15% mannose (sometimes lactose), 20-30% quinine hcl, and diphenhydramine or cimetadine. The latter three of these excipient ingredients are understood to function as antihistamines, anti-catabolic potentiators, and "taste-imitators".

"Yo mang, we f**king Aced that Laplacian Electrostatics final! We should celebrate seven thirty mang."
"we should get low
as f**k. lets hit the trap--ima call mah boy an let him know it's a bill eighty."
