A word commonly used in the eastern suburbs of Australia to describe half cast asian/aboriginal people. Extremely offensive.
Originated from the "colourless" watery fluid of the blood and nymph in biology to refer to "colourless" people in society.
Often "plasma people", are the victim of horrendous racial violence.
Look at that plasma cunt! He's too shit to even be a nigger! Let's BRAIN HIM!
