rasterbation

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.

Fred: "Hey, you guys wanna have a huge rasterbation session tonight?"
Tad: "You know it!"
