vanilla roller of unknown origin 

A random cigarette without any identifiable markings found rolling around in one's car which, upon smoking, tastes like vanilla. Sometimes contains things other than tobacco, such as marijuana, or oregano soaked in vanilla extract. You just never know.

"Dude, what the fuck is this?"
"Looks like a cigarette without identifiable markings rolling around in your car."
"Well fuck me blue and call me Cathy, it tastes like vanilla and asshole"
"Must be a vanilla roller of unknown origin"
