When one has inhaled enough smoke to the point of extreme euphoria, causing an epic high. Usually referred to the fine Purple Kush, but can be used any time whilst stoned.
boyfriend: im hella high
girlfriend: everything is purple...
boyfriend: maybe not as blown as you..

another wonderful example is the video "Purple Swag" by ASAP Rocky ~
