ying yangs

In order to "Get on the ying yangs" one must injest two different types of Heroin, ideally chinese white and black tar, hence the Ying and Yang. This enduces a powerful buzz that could satiate even the most starved fiend.

Old mate Peter showed me how to get on the ying yangs the other day.

Last we heard of Davo the mad cunt had tried his luck on the ying yangs.
