The act of smoking marijuana by one's self, esp. after failing to locate a partner to smoke with you.
"Annie and Jane said they wanted to blaze with me, but they left with Tom so now I'm stuck masturbowling."

You: "You wanna go get some food?"
Me: "Give me ten minutes, I'm trying to masturbowl in here."
You: "......whatever you do, please wash your hands."
