A mixture of Rastafarian-ism and masturbation, to "rasterbate" is the act of being stoned while masturbating.
After hitting the bong a few times, Jen and John went into the bedroom. Jeremy has no lady so he sat in the living room to rasterbate.

The action of masturbation while wearing a Rastafarian hat (preferably with dreadlocks) and smoking large sums of marijuana. Generally those who partake in this activity shout "yaman" at the moment of ejaculation.
