Spit on it... then pack it in a bowl...
This guy I know, I refuse to smoke joints with him because he uses so much spit that the joint won't even burn right...
The first time I smoked a joint with him I said "Dude your weed aint dried right"....
Then the next joint I watched him roll it.. and I was like "ewwwwwwwweewwwwwwww" You know like Ernest P. Worrel, Ewwww???
I was like, er, uh, no thanks, I'll pass, that first joint man, got me ripped! =)
