Rainbow Joint 

Rainbow Joint: a hand-rolled marijuana cigarette; consisting of 7 different strains of cannabis, wrapped in a wax (THC distallite) coated paper.

The 7 different strains represent the 7 colors of the rainbow; while the golden, oil-coated paper, the pot of gold.

Synonyms: Rainbow Blunt, 7 Dwarfs in a blanket.

The combination of the wax and 7 strains of bud in that rainbow joint got me ripped.

Rainbow Washing 

The Realization that you have been over pandered to.
