it means ur a prince nut..like if someone says somethin like "prince is the best nobody is better than him"...and a buncha other bull shit then someone usually says somethin like "dude lay off the purple kool aide"...understand?

it's a refernece to the mass suicide committed by the followers of Rev. J. Jones, in Jonestown.
Thry all drank poisoned kool aid at his behest when the authorities were coming down on him, and they did. Thereafter..ardent followers of a cause who follow blindly without thinking, are called Kool Aid drinkers. Like the wacko left
