This is when you smoke a joint by sticking the unlit end into the hole in the bowl of a pipe. It is so called because the joint looks like a birthday candle. You can burn a whole doob down to the ash like this. You can also fill the bowl with weed around the joint and get really crazy.
"This joint is getting to short to hold. Stick it in my pipe and we'll have a lil birthday bowl."
