milkshake

Prison slang.
A combination of urine, feces, blood, and semen, it's mixed and sits hidden from view. It is then thrown onto a passerby corrections officer. With luck, the C.O. will catch whatever STD the inmate has contracted.

Yo, that C.O. asshole is comin'
Get da milkshake and get 'im.
