Origin- I know it to be Italian - conchiglia- meaning shell...or shell covered.
My great grandparents were from Italy and this is what they called it. Everyone in our family uses the term.
"Molly!" Kelsey said, "your such a chonis!"
-derived from local stoners in sydney 2170,
slang produced- cones and from cones we got ownes, then to onis: pronounced as own-iss extensive shit talk took us to - chonis
singular = chone
-the act of pumping chonis
-one must release the shotty so the residual airflow sucks down the chonis into the water chamber
-mole smoked all the chonis
