Usually associated with the ecstasy experience but can also refer to a bowl of pot/weed/grass that is lit and is still burning. If a bowl is rolling there is no need to light it.
In relation to ecstasy, "Man, I took a molly about three hours ago and I am rollin'!"
In relatioin to pot,"Hey hit that quick, it's rollin' you don't need a light."
