What is Nigger Piss?
1.
Cheap, malt liquor like OE, Mickeys, etc. Black people don't have the money to by more pricier booze, so they blow it off on malt liquor which gets you trashed pretty fast, but tastes like shit. OE is also the color of piss.
Fuck OE I don't want none of that nigger piss!

2.
The foam residue after consuming a beer at the bottom of the bottle, can, or cup. Usually in excess after chugging
"He man I totally downed that beer before you!"
"Nah man you got some shit at the bottom!"
"Please, thats just the nigger piss that doesn't count!"
